Commit new website. The old site is tagged, so this won't change the live

site... but it does move HEAD on to the new site.

Too many changes to list really. General points are:

- Moved to a XHTML CSS compliant site.
- Reorganised the site into a more multi-project based look.
- Removed a lot of cruft.

Still to do:

- Fix all the zillions of bugs stopping the whole site from validating :-)
- Tidy up the HTML in terms of layout and indentation.

Thanks to AJ for his help this weekend in doing this.
