Allow moving after firing cleaver. This changes multishoot behaviour quite a bit. Needs a lot of testing.
Implements protocol message JOINING on frontend, so client in a room always displays correct room name, even when room name changes. Fixes
issue #522.
Removed in-lineedit labels such as "search:" and "room name:" due to size issues with localization and platform differences.
Send JOINING message in response to FOLLOW. Actual join may still fail due to room restrictions. Not tested.
