* Add remove view in dialtacts_activity.xml, and rearrange layout slightly
so that it takes up the same position in the layout as the search view
container. Contacts that are dragged to this remove view will be unstarred
and unpinned.
* Add drag event logic to the Remove View, so that when the user hovers a
contact over it, the UI will continue to respond. Previously, only the
PhoneFavoritesListView would detect touch events.
* Refactor DragDropController and OnDragDropListener into separate classes.
DragDropController performs the work of receiving drag/drop events from
multiple views, combining them, and then firing off callbacks as appropriate
to OnDragDropListeners. Each OnDragDropListener can then update their UI
or internal data model as necessary in response to the callbacks.
