Successful completion of #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

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