though it always acted like it did in the MODE line sent to the channel. This bug caused desynchs in some cases. Bug reported by Korfio (#0003048). - Fixes to SVSNICK: case-change no longer causes a collision, don't return the value from exit_client (which would be FLUSH_BUFFER), fix QUIT not being sent back on collision. - Fix for above so it doesn't -r the client.
