change muc window header when new messages appear
The muc window should change the window header when a new message comes in. Currently muc doesn't do this, but 1-to-1 chats do.
The workflow I'm in is I use ion3 as my windowmanager, and so I always see the window header, since ion has tabbed windows. I don't always see the window contents, though. So, anything that shows changes on the top left of the window title is helpful.
