Title: Add collectionView:didRemoveCell:forItemAtIndexPath: message to JNWCollectionViewDelegate

A message to notify the delegate when cells go off-screen. I have missed this for cells that need to have work started asynchronously and cancelled when they are scrolled through before the task finishes.
