[XML-SIG] XBEL: Lynx bookmark parser

[A.M. Kuchling]

Here's a script to parse Lynx bookmark files, and output them as XBEL.
It seems reasonable to modify ns_parse.py, msie_parse.py, and
adr_parse.py to always output XBEL.  I'm now also working on a SAX
handler that converts XBEL to a Bookmarks instance and then outputs it
in one of the browser formats.
