(svn r2152) - Fix: Chatbar in MP games is now on-top of the news window.
- CodeChange: Introduction of SendWindowMessage() where a window can send another window a message (ala windows style msg, wparam, lparam). Messages can be sent by windowclass and by windowpointer.
- CodeChange: IsVitalWindow() simplifies a lot of checks for window handling that need to know what windows it can close, or be on top of, etc.
