refreshed xwidget patch

[joakim]

The xwidget patch allows embedding of some gtk widgets including
gtk_socket in an emacs window.

I've put it in an git repos here(thanks to Daniel M. Hackney):

http://github.com/jave/emacs/tree/xembed

Its not production quality but still rather interesting.
Some further rambling notes are here: http://www.emacswiki.org/emacs/EmacsXembed

The file xwidget-test.el shows some tests, including embedding of emacs
in emacs, and the uzbl webbrowser!

The refresh fixes many annoying drawing bugs.
