Pass action info to the signal item_modified

Send action that modified the item. The receivers will have an easy way to determine what change have occurred.

there wasn't much to review. was some file missing?

https://codereview.appspot.com/12695043/diff/1/MoinMoin/items/__init__.py
File MoinMoin/items/__init__.py (right):

https://codereview.appspot.com/12695043/diff/1/MoinMoin/items/__init__.py#new...
MoinMoin/items/__init__.py:398: item_modified.send(app._get_current_object(),
item_name=self.name, action=action)
just "app" does not work?

how do you have enough data to show a diff if you don't give it here?

It will be passed here, but I thought to do it in the next cr/changeset. 
I can add it now, the title will be a little bit misleading though.

so you now verified that "app" is enough and "app._get_current_object()" is not
needed?
