Issue:
Interactive K-Means: Remove Highchart, other improvements
##### Issue

K-means depends on highchart. We'd prefer it didn't.

##### Description of changes

Other improvements:
- animate membership reassignment
- use domain model and context settings
- remove centroids by clicking
- UX simplifications - primarily targeting the most common use, that is, with painted data:
  - hide combos with variables when there are only two
  - show attribute names on axes, except when they are named x and y
  - hide axis when there are only two attributes, names x and y and from interaval [0, 1]
  - remove redundant elements (number of clusters, animation speed)
- use Orange's palettes
- prevent user from having more clusters than data points, instead of showing an error
- simplify the underlying kmeans code

##### Includes
- [X] Code changes
- [X] Tests
- [ ] Documentation

Gradient Descent: Remove highcharts, other minor improvements
##### Issue

Gradient Descent uses highcharts. We'd prefer it didn't.

##### Description of changes

I changed this one less than the other two (k-meand and polynomial classification).
- Replaced highcharts with pyqtgraph
- Simplified GUI (speed is fixed, attr y and target are hidden for regression, buttons are reorganized)
- Mouse cursor changes to crosshair and shows the cost at the hovered point (computed by learner, not from grid)
- Show when hovering over points on optimization path
- Contour lines are bold when hovered, cost is shown
- Widget uses domain context handler, models etc.

##### Includes
- [X] Code changes
- [X] Tests
- [ ] Documentation

Polynomial Classification: Remove highcharts, other minor improvements
##### Issue

Polynomial Classification uses highcharts. We'd prefer it didn't.

~~Doesn't pass tests on the oldest version of Orange, but should after merging #95, which increases the requirement.~~

##### Description of changes

Polynomial classification now uses the common `OWScatterPlotBase`.

Besides this,
- a few minor changes in GUI -- rearrangements and hiding of unnecessary controls
- removed option to set the contour step; 0.1 should be OK for everybody
- refactoring the methods

##### Includes
- [X] Code changes
- [x] Tests
- [ ] Documentation



Discussion / hints:
Much less clutter now.

In the usual scenario, with Paint Data, it also hides some redundant information (axis names, combos with attributes).

-    License who has not previously violated the terms of this License with
-    respect to the Work, or who has received express permission from the
-    Licensor to exercise rights under this License despite a previous
-    violation.
- h. "Publicly Perform" means to perform public recitations of the Work and
-    to communicate to the public those public recitations, by any means or
-    process, including by wire or wireless means or public digital

-
-3. License Grant. Subject to the terms and conditions of this License,
-Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
-perpetual (for the duration of the applicable copyright) license to
-exercise the rights in the Work as stated below:
-
- a. to Reproduce the Work, to incorporate the Work into one or more
-    Collections, and to Reproduce the Work as incorporated in the
-    Collections;
- b. to create and Reproduce Adaptations provided that any such Adaptation,
-    including any translation in any medium, takes reasonable steps to
-    clearly label, demarcate or otherwise identify that changes were made
-    to the original Work. For example, a translation could be marked "The
-    original work was translated from English to Spanish," or a
-    modification could indicate "The original work has been modified.";
- c. to Distribute and Publicly Perform the Work including as incorporated
-    in Collections; and,
- d. to Distribute and Publicly Perform Adaptations.
-
-The above rights may be exercised in all media and formats whether now
-known or hereafter devised. The above rights include the right to make
-such modifications as are technically necessary to exercise the rights in
-other media and formats. Subject to Section 8(f), all rights not expressly
-granted by Licensor are hereby reserved, including but not limited to the
-rights set forth in Section 4(d).
-
-4. Restrictions. The license granted in Section 3 above is expressly made
-subject to and limited by the following restrictions:
-
- a. You may Distribute or Publicly Perform the Work only under the terms
-    of this License. You must include a copy of, or the Uniform Resource
-    Identifier (URI) for, this License with every copy of the Work You
-    Distribute or Publicly Perform. You may not offer or impose any terms
-    on the Work that restrict the terms of this License or the ability of
-    the recipient of the Work to exercise the rights granted to that
-    recipient under the terms of the License. You may not sublicense the
-    Work. You must keep intact all notices that refer to this License and
-    to the disclaimer of warranties with every copy of the Work You
-    Distribute or Publicly Perform. When You Distribute or Publicly
-    Perform the Work, You may not impose any effective technological
-    measures on the Work that restrict the ability of a recipient of the
-    Work from You to exercise the rights granted to that recipient under
-    the terms of the License. This Section 4(a) applies to the Work as
-    incorporated in a Collection, but this does not require the Collection
-    apart from the Work itself to be made subject to the terms of this
-    License. If You create a Collection, upon notice from any Licensor You
-    must, to the extent practicable, remove from the Collection any credit
-    as required by Section 4(c), as requested. If You create an
-    Adaptation, upon notice from any Licensor You must, to the extent
-    practicable, remove from the Adaptation any credit as required by
-    Section 4(c), as requested.
- b. You may not exercise any of the rights granted to You in Section 3
-    above in any manner that is primarily intended for or directed toward
-    commercial advantage or private monetary compensation. The exchange of
-    the Work for other copyrighted works by means of digital file-sharing
-    or otherwise shall not be considered to be intended for or directed
-    toward commercial advantage or private monetary compensation, provided
-    there is no payment of any monetary compensation in connection with
-    the exchange of copyrighted works.
- c. If You Distribute, or Publicly Perform the Work or any Adaptations or
-    Collections, You must, unless a request has been made pursuant to
-    Section 4(a), keep intact all copyright notices for the Work and
-    provide, reasonable to the medium or means You are utilizing: (i) the
-    name of the Original Author (or pseudonym, if applicable) if supplied,
-    and/or if the Original Author and/or Licensor designate another party
-    or parties (e.g., a sponsor institute, publishing entity, journal) for
-    attribution ("Attribution Parties") in Licensor's copyright notice,
-    terms of service or by other reasonable means, the name of such party
-    or parties; (ii) the title of the Work if supplied; (iii) to the
-    extent reasonably practicable, the URI, if any, that Licensor
-    specifies to be associated with the Work, unless such URI does not
-    refer to the copyright notice or licensing information for the Work;
-    and, (iv) consistent with Section 3(b), in the case of an Adaptation,
-    a credit identifying the use of the Work in the Adaptation (e.g.,
-    "French translation of the Work by Original Author," or "Screenplay
-    based on original Work by Original Author"). The credit required by
-    this Section 4(c) may be implemented in any reasonable manner;
-    provided, however, that in the case of a Adaptation or Collection, at
-    a minimum such credit will appear, if a credit for all contributing
-    authors of the Adaptation or Collection appears, then as part of these
-    credits and in a manner at least as prominent as the credits for the
-    other contributing authors. For the avoidance of doubt, You may only
-    use the credit required by this Section for the purpose of attribution
-    in the manner set out above and, by exercising Your rights under this
-    License, You may not implicitly or explicitly assert or imply any
-    connection with, sponsorship or endorsement by the Original Author,
-    Licensor and/or Attribution Parties, as appropriate, of You or Your
-    use of the Work, without the separate, express prior written
-    permission of the Original Author, Licensor and/or Attribution
-    Parties.
- d. For the avoidance of doubt:
-
-     i. Non-waivable Compulsory License Schemes. In those jurisdictions in
-        which the right to collect royalties through any statutory or
-        compulsory licensing scheme cannot be waived, the Licensor
-        reserves the exclusive right to collect such royalties for any
-        exercise by You of the rights granted under this License;
-    ii. Waivable Compulsory License Schemes. In those jurisdictions in
-        which the right to collect royalties through any statutory or
-        compulsory licensing scheme can be waived, the Licensor reserves
-        the exclusive right to collect such royalties for any exercise by
-        You of the rights granted under this License if Your exercise of
-        such rights is for a purpose or use which is otherwise than
-        noncommercial as permitted under Section 4(b) and otherwise waives
-        the right to collect royalties through any statutory or compulsory
-        licensing scheme; and,
-   iii. Voluntary License Schemes. The Licensor reserves the right to

-    according to the corresponding provisions of the implementation of
-    those treaty provisions in the applicable national law. If the
-    standard suite of rights granted under applicable copyright law
-    includes additional rights not granted under this License, such
-    additional rights are deemed to be included in the License; this
-    License is not intended to restrict the license of any rights under

-    ----------
-    parent: QObject
-        Qt parent object, if any.
-    bridge: QObject
-        Exposed as ``window.pybridge`` in JavaScript.
-    options: dict
-        Default options for this chart. If any option's value is a string
-        that starts with an empty block comment ('/**/'), the expression
-        following is evaluated in JS. See Highcharts docs. Some options are
-        already set in the default theme.
-    highchart: str
-        One of `Chart`, `StockChart`, or `Map` Highcharts JS types.
-    enable_zoom: bool
-        Enables scroll wheel zooming and right-click zoom reset.
-    enable_select: str
-        If '+', allow series' points to be selected by clicking
-        on the markers, bars or pie slices. Can also be one of
-        'x', 'y', or 'xy' (all of which can also end with '+' for the
-        above), in which case it indicates the axes on which
-        to enable rectangle selection. The list of selected points
-        for each input series (i.e. a list of arrays) is
-        passed to the ``selection_callback``.
-        Each selected point is represented as its index in the series.
-        If the selection is empty, the callback parameter is a single
-        empty list.
-    javascript: str
-        Additional JavaScript code to evaluate beforehand. If you
-        need something exposed in the global namespace,
-        assign it as an attribute to the ``window`` object.
-    debug: bool
-        Enables right-click context menu and inspector tools.

-        The additional options. The underscores in argument names imply
-        hierarchy, e.g., keyword argument such as ``chart_type='area'``
