Changes on the new site

I have removed the Appendix category because I don’t think it ended up being very useful, and its content can generally be incorporated into Product or People pages. 

Similarly the FAQ only contained a few things that were permanently useful, which I have mentioned on the World of Sam page. The rest would be suited to forum topics.

The news category is straightforwardly replaced by the Forum. 

I've moved the useful; stuff from the FAQ into forum topics - can some of them be made sticky to keep their FAQ-ness :)
