Split app info into several screens

The root screen now only has the uninstall/force stop/disable buttons
and the rest has moved to sub screens listed in a preference list.
The root screen as UI approximate to the new mocks, but the separated
screens (storage, launch by default, etc.) have yet to receive their
visual overhaul.
