Don't commit snooze on horizontal swipes or when its in its expanded state

- Previously any touch outside of the snooze menu would commit the action
  (similar to how notification info gets reset) now only touches that
  aren't horizontal swipes will commit the action (if you snooze multiple
  in a row, it's jarring for the snooze item to disappear when you hit
  'down' on the next notification)
- Tracks expanded state of snooze menu
- Rather than commiting (i.e. snoozing) upon outside action when the
  menu is expanded it collapses the menu, upon next outside action snooze
  is commited
