bug#18812: 24.4; url.el user agent does not include Emacs version

[Phil Hagelberg]

The url.el functions for making HTTP requests set the User-Agent header
to "URL/Emacs" which is not very descriptive. It would be helpful to
include the Emacs version, at least.



In GNU Emacs 24.4.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.24.10)
 of 2014-10-20 on enigma
