Add /me messages to chatboxes (they're already in chatrooms)
.chat-body should have top rounded corners
Refactored status message rendering code

As a result we now implement more status codes from the spec.
Specifically the codes related to forced removal form the room

Also fixed a bug related to wrong authentication when logging in.
Enable user to reconnect to an open disconnected room

When a user has been removed from a room and the room is still open,
we want to re-use that same room once they join it again.
Use addHelpMessages method
Make sure chat-info msgs are not auto-removed
Re-minified JS and CSS
Merge branch 'master' into gh-pages
