Convert photo uploading over to the new model based validation

approach.

- Rearrange Simple_Uploader_Controller::add_photo() to validate
  the form early in the process, and switch to using model based
  validation.

- Move thumbnail generation into gallery_event::item_created() so
  that it's decoupled from the model.

- Delete photo::create() and move all of its logic into
  Item_Model::save().

- Add Item_Model::$data_file to track the data file associated
  with new movies and photos.

- Do some cleanup on the validation callbacks -- it turns out the
  2nd argument is the field name not the value.
