(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.

#include <stdio.h>

// This pretty simple file checks if the system is LITTLE_ENDIAN or BIG_ENDIAN
//  it does that by putting a 1 and a 0 in an array, and read it out as one
//  number. If it is 1, it is LITTLE_ENDIAN, if it is 256, it is BIG_ENDIAN
//
// After that it outputs the contents of an include files (endian.h)
//  that says or TTD_LITTLE_ENDIAN, or TTD_BIG_ENDIAN. Makefile takes
//  care of the real writing to the file.
