Revert "Framework: Remove Needless Preference"

This reverts commit 67c9c1ef04cf35cef6b3d4e6188d08e50a31aa7e.
Framework: Remove Needless Preference

PS2: Missed Line
PS3: Further Settings Clarification:
        If Reverse/State_one double
        click action: launch action
        long/short (they can still
        choose "skip" if they don't
        want to launch anything).

ClockActions: Dismiss Keyguard

Fix LockscreenTarget FC

Makes more sense to me anyway.
Main: If already unlocking don't
    attempt to unlock again (if
    user double-swipes target
    we currently hotboot)
