[PATCH] Add RSS support to hgweb

From: Goffredo Baroncelli <[e-mail]>

with the two small patches below, now hgweb can act as feed source.
Two kinds ofobjects can be tracked: the changelong and the files. This
can be useful if anyone would track the changes of a file ( and
because git has it, mercurial have to has ).

To check the changelog the url is
http://127.0.0.1:8000/pippo.pluto?cmd=changelog;style=rss

To check a file ( the mercurial/hgweb.py for examples ) the url is
http://127.0.0.1:8000/?cmd=filelog;file=mercurial/hgweb.py;filenode=0;style=rss

The first patch adds a new filter for the template: the filter is
named rfc822date, and translates the date from the touple format to a
rfc822 style date. The second patch adds the templates needed to
create the rss pages.

Tested with akgregator ( kde ).

[tweaked by mpm:

 add Content-type: text/xml
 add support for URL to header()
 add header with link and content type
 add RSS links on the normal pages]
