Feature #403 - Ability to delete media entries - Fixes according to feedback

*   Moved `mediagoblin.confirm` stuff to `mediagoblin.user_pages`,
    templates too.
*   Removed route extension for `mediagoblin.confirm`
*   Created `delete_media_files` which deletes all media files
    on the public_store when the entry is deleted
*   Created a new decorator to check if a user has the permission
     to delete an entry.
