This moves our site static files into the sitestatic directory if they
are shared resources, and also moves a handful of things (such as the
artwork logos) into application-specific static/ directories. This
allows the staticfiles contrib app to work after a few settings tweaks,
a run of collectstatic, and massaging the hardcoded '/media/' prefix out
of our templates.

Django 1.4 is going to make this a lot easier to move things to a CDN
and provides better template tags; for now this is setting the stage
before we can move to that.
