you can now create a comment with User#comment!(post, text)

So. It turns out that postgresql has a less-consistent idea of what .first means in an association with no default ordering. All the places we were doing bob.aspects.first (& etc.) needed to be more specific. & o ya, POSTGRES IS GREEN.

cleaned up indentation and spacing in controller specs.

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

refactored comments to work like status_messages in the controller.  weird stuff was happening when using EM::next_tick; holding off on that for now.

This reverts commit cb9fb0ad.
