Settings: Lockscreen Interface
Allow following actions with button long-presses on lockscreen:
- toggle flashlight (if available)
- play/pause/next/previous track selection

Allow customizing of back, menu, and home buttons. Search
button events are completely ignored on the lockscreen.

Auto-detect hardware keys, only show appropriate menu
options based on the actual hardware keys available on the
device (or completely hide if there are no hardware keys).
