*Integrate Script system to Core
-added ScriptMgr for loading scripts -removed bindings -moved script system to src/game -moved scripts to src/scripts -VC project files updated -cmakes updated (not 100% done yet) NOTE to Devs: -file locations changed -precompiled renamed to ScriptedPch -ecsort_ai renamed to ScriptedEscortAI -follower_ai renamed to ScriptedFollowerAI -guard_ai renamed to ScriptedGuardAI -simple_ai renamed to ScriptedSimpleAI -sc_creature renamed to ScriptedCreature -sc_gossip renamed to ScriptedGossip -sc_instance renamed to ScriptedInstance *use the new headers in scripts, thank you NOTE to ALL: cmake not fully tested, please report any errors with it could make creashes, incompability USE AT YOUR OWN RISK before further tests!! --HG-- branch : trunk
