Use separate domain for feed URLs

[timpritlove]

Feed URLs and the UI URLs should be decoupled, to free the user interface from restrictions and allow future changes.

Currently, both the UI and feeds are served via bitlove.org. Instead, feeds should be moved to the subdomain feeds.bitlove.org.

This can be achieved by issuing by changing the feed URL in the UI and apply a Permanent Redirect when the old URL is accessed by applications. After some time, most if not all clients should have accepted the new URL as most clients do understand the concept. Those who don't should get a bug report and take a class in web protocols.

Example:

A feed currently residing under

http://bitlove.org/metaebene/cre/feed

should be redirected to

http://feeds.bitlove.org/metaebene/cre
