[svn] * Reimplemented packet/update forwarding in more generic way

* Implemented far sight spells (Far Sight, Eagle Eye, etc) at unlimited range and properly forward packets
* Implemented bind vision spells (Mind Vision, etc) to forward packets at unlimited distance
* Implemented Sentry Totem (both vision switching/forwarding and alerting)
* Other misc possession fixes
* Added .bindsight and .unbindsight commands

Please test out the above spells (including Mind Control) and report any issues on the forums.
