Movement Functions
Use with caution - movement started by a script must be stopped by script. Keys/Mouse will not stop movement. These functions no longer work (fail silently) in patch 1.6 if NOT triggered from a hardware event (just like spell casts). As of patch 1.10 many of these functions were protected for use of only Blizzard signed code
