Code Issues Activity Actions

LibGUI: Give GTextEditor a context menu.

Browse source 
Now GTextEditor manages its own editing actions (cut/copy/paste/etc) and
will show a context menu containing them when requested.

Apps that want to put a GTextEditor's actions in its menu can get to the
actions via public getters. :^)
