Patch for html (`W h') with Gnus 5.4.62 and W3 3.0.93.

[Per Abrahamsen <abraham@dina.kvl.dk>]

This patch makes `W h' work for me with the latest versions of Gnus,
W3, and Widget.  I have never had it working before. 

I think it would be better to use `w3-region' directly in the
*Article* buffer, _and_ convert the *Article* buffer to use
`widget.el' for the buttons.  Since w3 is also based on `widget.el',
this should give you close to the full potential of w3 inside the
*Article* buffer.

It is a non-trivial piece of work, though.

	* gnus-art.el (gnus-article-treat-html): Use `w3-region'.
