Title: Add Delegate support for "shouldDeselect"

It looks like my implementation was a little bit too fresh, I ended up nuking the ability to have single selection in the gridview. So in order to make up for that, I've also added the "shouldDeselect" delegate calls to PSTCollectionView.

Sorry about the initial screwup.
