Code Issues Activity Actions

LibGUI: Make it easier to create checkable GUI::Actions

Browse source 
This patch adds GUI::Action::create_checkable() helpers that work just
like the existing create() helpers, but the actions become checkable(!)

Clients are no longer required to manage the checked state of their
actions manually, but instead they will be checked/unchecked as needed
by GUI::Action itself before the activation hook is fired.
