Update p5-XML-Atom-SimpleFeed to 0.82; changes since 0.8 include:

0.82 (2008-06-21)

* I can't believe no one noticed in such a long time that the XML
  escaping function was broken. I need unit tests

* Also, the date in the changelog entry for 0.81 was wrong.

0.81 (2008-06-21)

* Put private functions in XML::Atom::SimpleFeed::YeWhoEnters and
  placed methods in XML::Atom::SimpleFeed explicitly. This gets rid of
  approximately 734 prefix underscores.

* It turns out Carp::Clan wasn't even necessary, Carp works
  that way by default. *blush*

* More big POD cleanups (converted lots of list items to
  subheadings so they're linkable and listed in the TOC).

* Throw out the pointless POD and POD coverage tests.

* Automatically escape the content of the icon, id, logo,
  published, and updated elements. Oops. (CPAN RT #36961)
