Revert "Change the item rest update processing to call the

item::move(source, target) helper when the parent member has changed.
Using the move method insures that names and slugs that could conflict
in the target album are resolved properly.  Changed the item::move
method so it returns a message to be displayed if the caller chooses.
And changed the move controller to display the message returned by the
move if the item name was renamed as part of the move."

Rolling this back for a couple of reasons:

1) Bug in move.php ("message.info" is not a function name)

2) Having the message come back from the API call as a side-effect is
sloppy.  We should find a cleaner way to do this checking.

3) having item::move() call save() on any changed values in the ORM
is counter-intuitive.  Move should move, save should save.

I think the right approach here is to roll the move() code properly into
save().

This reverts commit 2492280.
