Core/ScriptSystem: Add compile time type check of function assigned to hooks - prevents incorrect function calls. Since this rev you have to put PrepareSpellScript(<yourscriptclassnamehere>) at the beginning of every spell script. Yes, i know it's unhandy, but unfortunately C++ preprocessor is very limited, so you have to do that extra work each time you write a script:(.
