Fix crash with some function hooks

Hooking functions that return float, ushort or byte causes a crash as the returned value will not match the expected type.
This fix will allow to return LuaFloat, LuaByte and LuaUShort instead.
Example hook that would crash without this: ItemComponent.DegreeOfSuccess
