Code Issues Activity Actions

LibGUI+WindowServer: Add support for enabled/disabled actions.

Browse source 
The enabled state of a GAction now propagates both to any toolbar buttons
and any menu items linked to the action. Toolbar buttons are painted in
a grayed out style when disabled. Menu items are gray when disabled. :^)
