Add undo snackbar for deleting items
- Add methods to ModelWriter to prepareForUndoDelete, then
enqueueDeleteRunnable, followed by commitDelete or abortDelete.
- Add Snackbar floating view
- Show Undo snackbar when dropping or flinging to delete target; if the
undo action is clicked, we abort the delete, otherwise we commit it.
