Simon Schampijer 6064fb30cc Add support for locking Palettes, SL #4008
This adds a property that indicates that a Palette should
behave in a locking manner. The behaviour is the same
as with the secondary Toolbars: when you hover over the invoking
widget the Palette will popdown and react to mouse movements,
leaving the invoker area or the Palette itself will popdown
the Palette again. When you click the invoking widget
the Palette will be locked. You have to unlock it again
to pop it down.

This patch makes the DescriptionButton and the Colorbutton
work.

If the DescriptionButton or the Colorbutton are placed in
the primary toolbar they will share the locked state with
the secondary toolbars. Only one can be locked at a time.

When a secondary toolbar is unlocked we do force that the
open Palettes are closed. Having a locking Palette in
a subtoolbar will also work (Activity Toolbar case or
ColorButton case in a few examples). There is no state
sharing implemented here at the moment, but so far we
do only have cases with one lockable Palette in a
subtoolbar.

This will also fix the case where we want to use the
OSK to edit the description of the activity SL #3887.
