Title: Added cancellation block into SZShareDialogViewController

I added a cancellation block into the share dialog view controller so when a user taps "cancel" in the share dialog, the button calls the cancellation block instead of the completion block. I also added a function in SZShareUtils to easily create this view controller with a cancellation block.
