ROMControl: GlowPad Torch (NavRing)

NavRing allows Secure Locks to use
    this feature as well.

PS6: Merge NavRing And LockRing torch into
    one spinner (only one active at once)
PS8: String edit
PS9: Fixed option showing up on devices
    that don't have torch if they clicked
    in the ROMControl>Lockscreens Glowpad
    Also did the same for SW600DP devices
    and the MinimizeChallenge option (they
    have this option hidden on create, so
    this was a bug for them as well).
PS10: Completely align spinner with other
    options
PS11: Rebase
PS12: Small reformatting to match
    AOSP guidelines
PS13: Missed a space
PS14: Despite not having merge errors
    Lockscreens.Java lost a lot of imports
    that were needed.
