Lockscreen : Bunch-o-fixes

- Prevent edge gesture from conflicting with lockscreen shortcuts
- Fix lockscreen shortcuts crash where animations were being run
  on detached view
- Fix statusbar flicker when swiping keyguard in from the left
- Fade scrim away when swiping lockscreen in and out
- Fix back button not working when showing bouncer in
  external keyguard.
- Ensure we collapse bottom area after up/cancel when
  in external keyguard
- Fix issue where clock/notifications can get off-center
  when swiping to left.
- Fix bottom flicker when swiping lockscreen to left
- Only lock directional swiping when swipe helper acknowledges it.
  This allows for all the standard swipe behavior to function.
- Ensure lockscreen shortcuts are not actionable when in SHADE
- Only dismiss bottom area after lockscreen shortcuts animations
  have finished animating
- Prevent swipe when album art showing
