squid-3 bugs page

Adri pointed out that the bugs page had broken html - I've fixed this.

Part of the problem was the .bug files, which get included in the
index.html file - please note that you should ensure the .bug files
contain only valid html.

I've added a link to the validator, if you're not sure whether a new bug
is valid or not...

Cheers,
ROb
