Merge lp:~cjwatson/launchpad/feedparser-5.2.1 into lp:launchpad

[Colin Watson]

Upgrade to feedparser 5.2.1.

This adds Python 3 support. I also want this because the previous version monkey-patched sgmllib, which caused weird problems with BeautifulSoup in some cases; this version no longer does that.

Launchpad only uses feedparser to get the latest entries from blog.launchpad.net for the front page, and I've verified that the results of doing that are identical with the old and new versions.
