RDG
(fixes bug FOR-430)

:

* Uses skinconf.xml to determine background and border color for notes, warnings, and fixmes;
* Uses skinconf.xml to determine background and border color for table cells (headers and data);
* Honors headings type set in skinconf.xml (clean|underlined|boxed) and colors headings accordingly;
* Uses skinconf.xml to determine font color for links.

In addition, this patch extends the "link" template to also apply to the "fork", "jump", and "a" elements.
Thanks to Florian G. Haas.
