by returning null instead of a filtered version.
- Changed the MuteDirector to implement ChatFilter.
- ChatDirector no longer needs a reference to the MuteDirector because
the outgoing mute-checking is now handled by the standard filtering code.
- Fixed a bug introduced by Walter back in December that caused the
MuteDirector to be _removed_ as a validator the first time you try to
/tell to a player that you've muted. How we never detected this, I'll
stay awake at night wondering...
