add scenario support

something like that

public static class Scenario
{
	public static bool IsStepComplete(int step)
	{
		return (Lua.LuaDoString("local _, _, numCriteria = C_Scenario.GetStepInfo(); if not numCriteria or numCriteria == 0  then completedObj = 'true'; return; end; local critID; _, _, completedObj,_,_,_,_,_,critID = C_Scenario.GetCriteriaInfo("+step.ToString()+"); ", "completedObj").ToLower() == "true");
	}
}
