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.
