Spoike b937bb8161 server now claims to be proquake-compatible, so will use 16bit angles for proquake and its nq clones. 
fixed an angle size issue with fitzquake. this was not an issue when only the rmq protocol was used as the server forced all angles to 16bit anyway, but does matter if the server is using the same basic protocol without angle extensions.
