Implement most of the remaining client-side GM commands

* Muting a player's freechat
* Kicking players
* Querying info about a player
* Teleporting yourself to a player
* Teleporting a player to yourself
* Teleporting a player to another player
* Teleporting a player to arbitrary coords
* Teleporting a player to arbitrary coords in an arbitrary mapnum
* /unstick

Also:
* Renamed misleading setSpecialPlayer() to setValuePlayer()
* Revamped monitor logic
* Added server-side checks to account level 50 commands
* Made sure even trade chat is run through sanitizeText()
* Moved setSpecialState() closer to its calling functions
* Interpret client commands even in Buddy and Group chat (but not in
Trade chat)
