2004-02-23  Rob Adams  <readams@readams.net>

	Add my copyright notice to a number of files on which it should
	already exist.

	* src/window.c (meta_window_notify_focus): modify code to move to
	front of MRU list so that we can have an assert that it was there
	in the first place.  This code may be causing some crashes.  See
	#131196.
