Title: ensure that the user can quit a pick activity even if an overlay is displayed

This pull request makes the gallery overlay dialogs property opaque to touch events, and then puts the back button displayed by the Pick activity over top of the overlay so that users can back out of a pick even when the gallery app is displaying one of its overlays.

Fixes #4725
