A circular reference bug fix suggestion and a Chinese internationalization file support

[DeveloperJx]

I found a slight problem may cause memory leak,and here are the steps to reproduce:
Firstly,open your example project.Then open the Main.Storyboard and add a storyboard id to the layout of ViewController as shown in the screenshot:

Secondly,open AppDelegate add source code UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "test") to the callback method "didFinishLaunchingWithOptions" as shown in the screenshot:

Finally,run the app,then you can see xcode detects a memory leak form the member variables of PermissionScope as shown in the screenshot:

So,I suggest to add a weak mark to the member variable named viewControllerForAlerts of PermissionScope.And hope it could eliminate the risk of memory leaks.

Thanks for your open source library!And hope you have a nice day!

是真的circular引用了 ！ CPU资源竟然多走了20几M！
