HOVER: Respect screen limits when adding view

As for what @Decad3nce reported here http://review.cyanogenmod.org/#/c/66654/
we shouldn't keep FLAG_LAYOUT_NO_LIMITS so view doesn't exceed the screen limits.

Thank you Adnan :)

HOVER: Don't treat touch outside event as true if is animating

- It needs to wait animation to be finished to start listen for touch outside
  and runs hide timer.

SwipeHelper: Ignore ACTION_OUTSIDE touches

  When using the swiper class within a layout like a notification container
  elsewhere the notification shade, when tapping outside even if the finger will
  not move is easy to detect an ACTION_MOVE event. That will consider it like a
  dragging event and the view swipes to left a bit on its own getting stuck
  until next touch. Break if tapping outside, so it doesn't go mistakely forward
  to ACTION_MOVE event case.
