		Since on win32 platform, 'reinterpret_cast<long>(typeid(*native_obj).name());' invoking in cocos2d.dll and outside cocos2d.dll(in TestJavascript.exe) will return different address.
		But the return string from typeid(*native_obj).name() is the same string, so we must convert the string to hash id to make sure we can get unique id.
