More sensible error message when a skeleton to refresh in the 3d view
has been joined into another and therefore does not exist.
Connectivity widget: draw charts of number of synapses vs number of partners,
for the active or all selected skeletons.

The color palette for the bar chart needs work.
Check that any partners exist prior to trying to find out their synapses.
Addresses the error message seen when using AND in the connectivity widget
and no common partners exist.
Make argument be direct rather than a keyword argument.
Update "Projects > Open" menu when a data view is loaded

When normal data views were loaded, the "Open" submenu within the
"Projects" menu, wouldn't have any content. This commit fixes this and
triggers an update of the menu when a data view is loaded.  Fixes #535.
Added "Measure" button to Selection Table, which opens the Skeleton Measurements Table
which contains cable length, smooth cable length, and info on nodes and synapses
for every selected skeleton in the Selection Table.

Allow HTML code in notes/comments of menu items

If a menu item has a note/comment associated, it now is renderd as-is.
This means they now can contain HTML code (e.g. links) and let the
browser render it. Each note is embedded in a div of the class
"menu_item_note" to make the display easier adjustable. This commit
fixes #536.
webglapp: skeleton text tags are not created by default but on demand.

Fixed error in creating text tags, was only creating one single tag
of each kind instead of as many as necessary.

Found accidental global variables (camera, sphere) and made them local.

Fixed error in variable name "ambienteLight", now there is an ambient light.
