php mailing list feeds in rss 0.93

[Jim Winstead <jimw-yahoo@trainedmonkey.com>]

i added a little bit of code to the news.php.net nntp and http gateway
to the php mailing lists to also support rss 0.93 feeds of the recent
posts. for example:

  http://news.php.net/group.php?group=php.dev&format=rss

there's links to all of the rss feeds on http://news.php.net/

(yeah, 0.93 is just a proposed format right now, but the only thing
that seperates this feed from a 0.92 feed is the use of the pubDate
element on the items. a link to the author as the description element
is probably more questionable. maybe 0.93 should add an author
element. or i guess i could use the source element.)
