Added feedparser as a requirement in order to fetch the feed.

Added beautifulsoup4 to easily parse and modify the html markup that is
part of the feed.
Added a new app, utils, which we can use for reusable code which does
not belong to a single app.

Added a templatetags directory to the utils app and created a
'pull_feed' inclusion tag. This allows us to pull a feed into any
template where we want it.
