Handle global keybindings in the shell

Handling global keybindings, such as volume and brightness keys but also custom keybindings, directly in the compositor is the only way to deal with grabs and modal operations that could be active (primarily the overview, for which special policy was introduced in the last commit) https://bugzilla.gnome.org/show_bug.cgi?id=613543
Prefix keybinding names with 'internal-keybinding-'
