Code Issues Activity Actions

LibGUI: Search for actions with a Shortcut instead of for KeyEvent

Browse source 
Instead of having widget/window/application create a shortcut from a
KeyEvent within their find methods, we'll just pass them a Shortcut
so that the "where to search" logic doesn't need to be duplicated
for different Shortcut types.

It also lets us handle invalid Shortcut rejection at a higher level,
with most things letting the caller be responsible for not searching
for actions with an invalid shortcut.
