LYNX-DEV LINK REL=xxx patch (a bit long)

[Benjamin C. W. Sittler]

This patch is against Lynx 2.6 with Fote's 1996.12.20 mods. I wrote it
after reading the (now expired) draft-ietf-html-relrev-00.txt, which
discusses the LINK and Anchor attributes. According to this draft,
Forward, Back, and Home are reserved for browser internal use!

If you wish to conform to this draft (still cited in HTML 3.2 as the
reference LINK REL and REV values!) I suggest you change Forward to Next,
Back to Previous, Home to Top, Up to Parent, and Help to Navigator.
