Detailed Description

Don't make ScriptEngineProtocol inherits from Object since setScriptEngine is invoked only once in AppDelegate.cpp, It will affect the lifecycle of ScriptEngine instance, the autorelease pool will be destroyed before destructing ScriptEngine.

So a crash will appear on Win32 if you click the close button. @js NA
