Address references to *.hint with some exceptions

In years < 2001 (with the exception of ferguson2/) that still have
reference to *.hint files they have been changed to README.md with the
following exception: in 1998/dorssel there was a dorssel.hint2. This was
changed to dorssel.hint since the dorssel.hint was changed to README.md
a while back. The references to dorssel.hint2 were changed to without
the 2.

There was an out of date reference in faq.html file to a .hint file as
well that was updated to README.md; the dorssel2.hint in years.html was
changed to the new name.

With that the only files that have to be updated are those that are >=
2001. I still have to check for hint.* however.
