||Remove explicit wiki.call-cc.org hostname from intrawiki links
Strip hostname from all intrawiki links, making the URL relative
but leaving the path as absolute. This permits offline qwiki use.
References to /chicken-projects (egg index, RSS) were left as-is.
Also removed most percent encoding, as it's not currently handled
well by qwiki or chickadee, and spaces work fine in source URLs.
