Report with lots of hyperlinks

[Ian Lynagh]

Hi

I've rewritten the syntax section (appendix B) in docbook, slightly
hacked the nwalsh style sheets and produced

http://c93.keble.ox.ac.uk/~ian/report/html/

The lexical Structure section is also just started more as
proof-of-concept for linking back into the rest of the report.
As well as adding hyperlinks between the nonterminals I've tried to
distinguish between terminals and the operators better, but I don't
think I've been very successful.

Don't know if anyone else will be interested in this, but if you are
then there you go  :-)
