Make it possible to specify custom URLs for feeds.

Browse source 
With this patch, there are new FEED_*_URL configuration options that
allow to specify custom URLs for feeds, which is helpful in case the
feed filename and the actual URL differ a lot -- for example if a feed
is saved to

    blog/feeds/all.atom.xml

but the actual URL from the user PoV is

    http://blog.your.site/feeds/all.atom.xml

This setting currently affects only the generated feed XML. This change
is also fully backwards compatible, so if the FEED_*_URL setting is not
present, the value of FEED_* is used for both file location and URL.
