[emacs-wiki-discuss] patch for alt. text in image links

[Christoffer S. Hansen]

This patch fixes a bug in version 2.69 that didn't publish alt. text in 
image
links correctly:
[[*web-link*][*image* *alt*]] => <a href="*weblink*"><img 
src="*image**alt*" alt="" /></a>
What emacs-wiki should do, and this patch fixes, is the following:
[[*web-link*][*image* *alt*]] => <a href="*weblink*"><img src="*image*" 
alt="*alt*" /></a>

Two changes are made:
emacs-wiki-image-regexp is changed to accept alternative text, and
the emacs-wiki-inline-image function in emacs-wiki-colors.el is altered 
to work with the new image definition.

Note, however, that the patch will not work if there are whitespaces in 
image
filenames.

I hope this is useful. Comments are welcome

Regards,
Christoffer S. Hansen

[[CamelCaps]] or include a leading slash - [[./text]].
