[GNU ELPA] Proposed new package url-scgi.el

[Stefan Kangas]

I would like to propose adding url-scgi.el to GNU ELPA.  It implements
the SCGI protocol for url.el, and can be found here:

Up until now, it has been developed as part of my mentor.el, that
implements a frontend for the "rtorrent" bittorrent client.[1]
The main motivation for breaking this out into it's own package is to
have a clearer separation of concerns for mentor.el.

This library is obviously quite niche, and is not likely to see a great
deal of interest.  But having it as it's own package might make it a bit
more discoverable, and it does add useful functionality that some might
be interested in.
