LibGUI: Allow finding the source of a GAction activation

Browse Source 
When a GAction is activated by a menu, or by a toolbar button, you can
now use GAction::activator() to get a pointer to whomever activated it.

This can be used to implement context-specific behaviors in situations
where the same action is exposed through multiple paths.

This addresses an issue that was brought up in #826.
