Add completion block parameters to performAction:animated: methods of M13ProgressHUD

[BigSauce]

I would like to segue to different controllers after, and only after, animation of the progress HUD is finished. For example, when upload succeeds, I wanted to segue after the success animation is finished. Same thing with failing.

It would be great to have completion blocks for this. Thanks!

That is a good idea. I will work on that when I have time. If you want it sooner, I would suggest a pull request. If someone wants to implement this, I would have the whole implementation of this be in the base class for all the progress bars.
