Bug fix in selection and current source selection in Geometry view.
+ various improvements in other views.

Bugs fix with selection & non-modifiable source.

Bugs fix with selection.

Correct behavior for non-modifiable source in every view (i.e. disable motion).
GUI minor fix (label of bool property in property manager, font, session switcher for instantaneous).

Bug fix ; avoid selecting the selection recursively.

Fixed zoom best fit for geometry view (using method to compute bounding box).

Added actions "Invert selection" and "clear selection".
Changed label of Bool Property to 'on' / 'off' (instead of 'true' / 'false')

Added actions "select current" and "select all".

Implemented correct scaling and rotation of SELECTION (multiple sources) in the Geometry view.
Improved the mechanism for cursor in ViewRenderWidget (to enable cursor on selection too) + eye candy for delay cursor trace.

Implementation of method unsetCurrentSource() in rendering manager (for code clarity).
Implemented 'currentSource' pointer and mechanism for geometry view; the source currently manipulated being possibly the View::selectionSource (not managed by rendering manager);
