url-dired.el requires w3

[Diane Murray <disumu@x3y2z1.net>]

(url-retrieve-synchronously "ftp://ftp.gnu.org/") opens a dired buffer
in `url-dired-minor-mode'.  Pressing RET on a file there calls
`url-dired-find-file', yet url-dired-find-file uses `w3-fetch' and
`w3-open-local' which are not part of Emacs.  The following patch
changes it to use `find-file'.  w3 has its own w3-dired.el file, so
users of w3 will still have that functionality.


	* url-dired.el: Don't require w3-fetch and w3-open-local.
	(url-dired-find-file): Use `find-file'.  Doc fix.
	(url-dired-find-file-mouse, url-dired-minor-mode): Doc fix.
