Code Issues Activity Actions

LibGUI+WindowServer: Add "visible" state to GUI actions

Browse source 
This patch adds a visibility state to GUI::Action. All actions default
to being visible. When invisible, they do not show up in toolbars on
menus (and importantly, they don't occupy any space).

This can be used to hide/show context-sensitive actions dynamically
without rebuilding menus and toolbars.

Thanks to Tim Slater for assuming that action visibility was a thing,
which gave me a reason to implement it! :^)
