Lockscreen Longpress: Unlock Logic

In my opinion, we should unlock after
    user removes their finger.
This matches short-press unlock better
    and allows the user to change their mind
    on a target (I do that a lot).
Added a vibration action on longpress
    being true.

Reduce observers in SystemUI: KeyButtonView

This is based on the work by Jens Doll for the StatusBarIconView

The ContentObserver class will be a singleton, so there is only
one observer for all buttons.

On my Nexus 10 it reduced the observer count from 48 to 4.

This version fixes the funky glow effect.
