When deleting a Podcast (module version: 2009072101) there is no warning when deleting a podcast episode.

To replicate:
1. User adds podcast episode
2. User clicks 'Edit items' tab then
3. User clicks 'Delete item' next to relevant episode

What happens: the item is deleted immediately

What should happen: the user should be prompted to confirm they would like to delete the episode. When confirmed the item should be deleted, if the user cancels the item should not be deleted.
