Fix menu and various other fixes

The menu in all html pages for the FAQ was fixed to link to the step 0
(of how to enter the contest) and also it was renamed ('Enter the
IOCCC').

I also went through the most important sections of the FAQ (how to
enter and the mkiocccentry related questions) and checked the
register.html, pw-change.html and submit.html pages. It is possible I
have missed something but I think it's in pretty good shape nonetheless.
