#59 Alternative RSS feed

[Steve Pugh]

The patch adds an alternative RSS feed to the default one.

It can be switched on or off using the static variable
in com.arsdigita.london.rss.ui.ChannelGenerator
(perhaps a parameter would be better for selecting this)

It basically customizes the RSS feed for various
fearures we required:

1. Control of xml output for specific item types, in
partulcar, date information included in feed for
PressRelease and Newsitem types.
2. Shows additional info such as live and draft id.
3. Allows filtering to defined content-type only (using
a request parameter)
