Fixed ws tp, updated target code to use new SetTarget, added aggro detection, Fixed waypoint routing.

Added some support for current retail client. Fixes to the code were:

* Change from using 100tp to 1000tp for weaponskills.
* Change from using FFACE.Target.Type = Mob aggro detection to a more
robust form in UnitService.cs.
* Change from tabbing to find target to scanning memory with
UnitService.
* Fixed errors with waypoint routing where an index out of bounds error
would be thrown.

Still lots of work to do to get it release ready again. Bot ends up
frozen and I'm not sure why yet.
