Activity feed "broken" for deleted remote branch

Created by: rdlowrey

I noticed today that if you delete a remote branch the relevant activity feed entry looks like this:

It just says "user on branch" ... which is not very helpful.

Deleting bugfix branches is a normal part of the git workflow and it would be nice if the activity feed gave some indication of what was going on when you performed this action.

Thanks @rdlowrey. I think this is due to us not recognising the event that github is sending us.
