This reverts commit 902c40e4.

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.

Added Foreman gem.  Run Diaspora using `foreman start` (will start everything except mySQL.  Passing in a -p flag will let you specifiy the port.  Also: I took single_process_mode out of app config and made it an environment variable.  If you want to boot a lightweight server, run `SINGLE_PROCESS=true rails s`.

Moved post/comment text collapsing into respective widgets; removed from stream.js.  Removed an unused function in stream.js (image hotlinking).

Use explicit parameters instead of request format to determine whether we render a remote or non-remote form in aspects#new.
Facebox needs to get back a text/html response. We were using text/javascript to indicate that we wanted a remote form and text/html to indicate we wanted a non-remote form. The trouble is, if we request with text/javascript then that is the format we get back. It doesn't really make sense to use formats that way anyway, so I changed it to an explicit parameter. This had the nice side effect of simplifying our new-aspect views.

condense asset declarations; include all js in widget and helper directories (this is what we've already been doing)
