Add the skeleton for the New Profile System.

 The idea of this widget is to display and edit the profile.

It has:
 1 - ToolTip / Legend item, displays every information of the current
     mouse position on it, plus the legend for the maps.
 2 - ToolBox, displays the QActions that are used to do special stuff
     on the profile ( like activating the plugins. )
 3 - Cartesian Axis for depth ( y )
 4 - Cartesian Axis for Gases ( y )
 5 - Cartesian Axis for Time  ( x )

It needs to be dynamic, things should *flow* on it, not just appear / disappear.
It's the last attempt to create a QGraphicsView based Profile System,
as the next will most probably be written in QML.

Added a new class based on QGraphicsRectItem that can be animated.

This class extends the QGraphicsRectItem with the ability
to use the Qt Property System - and thus, we can animate
the properties. Initially I put only the rectangle, the
position and the x and y positions indidually for testing.

Added a QGraphicsPixmapItem subclass that handles Animations.

This class is useful for adding / removing icons on the future profile in
a way that they are smoothly added to / removed from the canvas.
It uses the QProperty System to deal with animations.

Added a class based on QGraphicsLineItem that can be animated.

This class has animatedHide, animatedMoveTo and QProperty
animations. it's very userful for the future creation of the
Cartesian Axis that will have the ticks 'flowing' around when
it's needed.

Add a class based on QGraphicsSimpleTextItem that handles animations.

This commit adds a class based on QGraphicsSimpleTextItem that
handls animations via animatedHide() animatedMoveTo() and a few
other QPropertyes. This is to be used in conjunction with the
DiveLineItem added in the past commit on the Coordinate Axis.

Added a new Namespace to deal with Animations and related functions.

Since the animation methods are fairly the same for any QGraphicsItem,
I created a new namespace named 'Animations' that should handle all
of the specific Animation Functions there, and the programmer has to
call those functions from the objects. Good thing is that this reduces
boilerplate code.

Cartesian Axis, based on the Ruler class on the Dive Planner.

This is the same class as the Ruler, but uses the DiveLineItem
and DiveTextItem classes created to make it animateable. The next
few commits will work on that part. The Ruler was a very bad
name for a class that's actually an Axis, that's why I depreceated
the later.

Remove only the Uneeded Ticks / Labels when a update is requested.

This patch makes the updateTicks method not remove / readd everything
when it's triggered, but to only remove the ticks / labels that
are no longer needed on the current display.

Moves the remaining ticks of the Axis to their correct position on update.

If the size of the Axis changed, this should move them smootly to their
place.

Added the remaining of the ticks to their correct position.

When we prepare the axis to show something on the Profile
we need to add the remaining ticks to show on screen,
Since this method tries to animately move / remove things
before calling this.

This has no animations yet - will have in the future.

Added a Model that should handle the Dive Profile

This model encapsulates the plot_info struct and provides
a consistent way to show it using the Qt Model view system
in the C++ and QML way. For a QGraphicsItem that should show
a Profile, this is the start.

Added the DiveProfileItem that uses the DiveProfileModel to diplay data.

I've used the paint() method on it ( even if it's not necessary
on a QGraphicsView ) to reduce absurdely the number of items that are
inserted on the QGraphicsScene ( each small line of the profile should
be an item if it was not for this, it's like that on the old profile. )
and thus reducing the memory consumption, speed and so on.

Pass the current selected dive to the new Profile Widget.

This call just passes the selected dive to the new profile widget. No
drawing is performed, I still have to setup the constructors and the rest

Added a 'Depth' Axis that knows how to add its strings on screen.

The CartesianAxis used a simple method to put things on screen
which is wrong for almost any case besides the 'current value here'
since we store things in milimeters on the axis, we need to convert those
to meters before showing on the profile.

Create a Time Axis that knows how to plot the minutes.

Created a Time Axis based on the CartesianAxis that knows
how to plot the minutes. This is needed because the CartesianAxis
donesn't knows about minutes at all, and would plot the
seconds instead.

Added the flag to ignore item transformations on the background.

The background should be a Pixmap and thus it cannot zoom in or
out; this keeps it the same size always, the full height of the
scene.

Started the work on the States for the Profile.

This is a start of the work on the States for the Profile.  All setup is

never worked with QStateMachine before, but it seems to work correctly.

Added Constants to the code, to ease the setup of the transitions.

Those constants will be used later on to setup all transitions of
the Graphics Items on the canvas. They are the correct positions
of each item inside and outside of the scene, in a way that the
state machine can animate them smootly.
