DC DG; added LastThreeComments decorator so we don't have to load those comments when not needed (i.e. new profile pages)

and comment presenter

MS DC; text now overlays for wallpaper; ALSO. really sorry @danielgrippis stuff does not work in firefox.  or safari.

or konqueror. we will talk to him about it later

introduce the idea of Federated::Base. this is mostly just renaming and collasping of different federation modules, but also starting a direct hiearchy of these federation classes to make everything easier to refactor

phasing out app.user() for app.currentUser

the previous and next posts are now supplied in json of the presenter; give the template creator a default value

collapse Post#last_three_comments and Commentable#last_three_comments, do not double query comments in CommentsController#index for a JSON response, remove spec that tests ordering as it's not deterministic on psql without specified order

don't use .last(3), use .limit(3) instead.  also, don't put an order on an association as it isn't overridable.  (this commit minimizes AR object instantiation in the stream)

commit. Add migration and rake task to copy hidden information from
share_visibilities to users. see: http://devblog.joindiaspora.com/?p=44

remove cache counter for photos, as it was causing too many edge-case errors & added complexity across models

only load photos for a post if photos_count > 0; display 'limited' or 'public' in stream elements; fix small like bug in stream

remove widget references on backbone stream pages; don't call time_for_stream if @backbone (the method references @stream.stream_posts)

corrected template views; status message now includes oembed; updated post.rb api to supply oembed and object_url
