Successful completion of `#409 </issues/409>`_ (media submission
success messaging) leaves some debris to clean up

these aren't actually used anywhere


-  submit\_success view
-  mediagoblin/submit/success.html template
-  mediagoblin.submit.success route

Main page and user page show media galleries. They should be
showing them in reverse order they had been submitted and not
according to ascending document id as they are now.

For that we simply need to append:

::

    .sort({'created': -1})

to the find() query.

While we are it, we should add

::

    .skip(0).limit(30);

too (using variables with those defaults), so we can easily do
pagination later.

Right now we're using Google's Web Fonts embed code:

`http://www.google.com/webfonts/family?family=Carter%20One#code <http://www.google.com/webfonts/family?family=Carter%20One#code>`_

This retrieves the font files from Google's servers. In the future
we should store the files locally.
