* Fixed a bug that replayed old cached appearance when changing outfits 

* Added suser(bad client) DOS protection by limiting the max cacheitems to the maximum sane amount.
* Prevents potential numerous loops from running amok and index errors if the client purposely provides bad cache info.
* If the XBakes service wasn't running, the SetAvatarAppearance routine would crash when contacting the XBakes service even though it was in a Try/Catch for the appropriate error type.  It only properly error handles with the type Exception :(.  (commented on that because it's unusual)
