05.12.99 
    - fixed sound bug (I reinstalled my system, new SDL and so on, and the
	                   sound doesn't work on this system ... damn if no one
					   mail me bug reports, I can't find all bugs on my system,
					   on my computer the game runs)					   
	- added window mode support (xcrillion -w)
	  (you should only use them with SDL 1.0.0+)
