This is a horrible hack, but it seems to mostly work. It does a
few things:
1. Transforms references starting in http:// to footnotes with the
appropriate hyperref macro to make them clickable. (This needs
to be expanded to deal with news: and needs to be adjusted to
deal with "#", which is creating bad links at the moment.)
2. For intra-document references, constructs the appropriate absolute
reference using a latex \pageref.
This involves applying a simplified version of the
general URL resolution rules to deal with ../. It only works for
one level of subdirectory.
3. It is also necessary to deal with the fact that index pages
get references as "/".
