RSS and Atom now handled by latest version of magpierss (magpierss.so…

…urceforge.com). class.RSS.php was a renamed include file from magpie which was 2 versions old. I've reworked the code to use the official magpie release which should allow for easier upgrades in the future.

-/**
- * NOTES ON RSS PARSING PHILOSOPHY (moderately important):
- * MagpieRSS parse all versions of RSS with a few limitation (mod_content, and
- * mod_taxonomy support is shaky) into a simple object, with 2 fields,
- * the hash 'channel', and the array 'items'.
- *
- * MagpieRSS is a forgiving and inclusive parser. It currently makes no
- * attempt to enforce the validity on an RSS feed. It will include any
- * properly formatted tags it finds, allowing to you to mix RSS 0.93, with RSS
- * 1.0, with tags or your own imagining. This sort of witches brew is a bad
- * bad idea! But Magpie is less pendantic then I am.
- *
- * RSS validators are readily available on the web at:
- * http://feeds.archive.org/validator/
- * http://www.ldodds.com/rss_validator/1.0/validator.html
- *
- */
-
-/*
- * EXAMPLE PARSE RESULTS:
- *
- * Magpie tries to parse RSS into ease to use PHP datastructures.
- *
- * For example, Magpie on encountering RSS 1.0 item entry:
- *
- * <item rdf:about="http://protest.net/NorthEast/calendrome.cgi?span=event&#38;ID=210257">
- * <title>Weekly Peace Vigil</title>
- * <link>http://protest.net/NorthEast/calendrome.cgi?span=event&#38;ID=210257</link>
- * <description>Wear a white ribbon</description>
- * <dc:subject>Peace</dc:subject>
- * <ev:startdate>2002-06-01T11:00:00</ev:startdate>
- * <ev:location>Northampton, MA</ev:location>
- * <ev:enddate>2002-06-01T12:00:00</ev:enddate>
- * <ev:type>Protest</ev:type>
- * </item>
- *
- * Would transform it into the following associative array, and push it
- * onto the array $rss-items
- *
- * array(
- * title => 'Weekly Peace Vigil',
- * link =>
- * 'http://protest.net/NorthEast/calendrome.cgi?span=event&#38;ID=210257',
- * description => 'Wear a white ribbon',
- * dc => array (
- * subject => 'Peace'
- * ),
- * ev => array (
- * startdate => '2002-06-01T11:00:00',
- * enddate => '2002-06-01T12:00:00',
- * type => 'Protest',
- * location => 'Northampton, MA'
