Core/AI: implemented SmartScripts System (still beta) not 100% complete

WARNING: Use scripts at own risk. You were warned.
NOTE0: creature, gameobject, areatrigger type scripts should be fully functional
NOTE1: has no effect on any core related stuff if not using any SmartScript
NOTE2: all event/action/etc descriptions can be found in SmartScriptMgr.h

SmartScripts is a reloadable DB-Sript system, with full control for special scripting,
like escorting, following, complex combat handling, pre-stored AI templates(caster, turret, etc) and much more
with a total of 66 events, 78 actions, 22 target types, and can be easily extended
