Let delegate control stuff

[Arthraim]

Hi @chiunam

Love your work a lot, until I found this design may cause some weird bugs.

What Did I change?

no dismissViewControllerAnimated:completion: call in -dismiss when -assetsPickerControllerDidCancel is implemented

Why?

1. If you don't implement imagePickerControllerDidCancel:, UIImagePickerController just does't do anything. So, I hope CTAssetsPickerController could stay consistent.
2. User may want to use other method to dismiss your picker. (Like if I add the view directly to somewhere as a subview, then I want to dismiss it by removing it from super view. That's extremely bad practice though.)
3. Lost control of completion block of dismissing.

I just deleted the dismissViewControllerAnimated:completion: at first, then I think if user doesn't implement -assetsPickerControllerDidCancel, it should stay what it behaves as you designed, so I put it in an else.

Hope you agree with my thoughts. :D

@Arthraim Thank you. That's sound reasonable.
