This reverts commit 017251fe.

Change prune_aspect_ids to aspects_from_ids, seperate out non-backgroundable piece of posting from dispatch_post

move photo-show js to assets.  remove EM::next_tick from controller#create actions.  make photo show pages render again.

photo show links to original post and siblings.  status message shows all photos associated with it.  youtube player makes http/s call instead of just http.

profile photo uploader is now a standard form file element.  Upload new image through people#update, which calls current_user.post to do so.

photos do not require an album.  uploading files on a user's photos#index page will post to all aspects.

Also, added attr_protected to Photo#person and Photo#person_id.
