VuXML.org improvements

[Jacques Vidrine]

Hello Everyone,

I have made a few small changes to the VuXML.org web sites,
    http://www.vuxml.org/freebsd/  (aka vuxml.freebsd.org)
and http://www.vuxml.org/openbsd/

- Date-oriented indices (e.g. entry date index) visually group entries
  from the same date.

- The package name index is more useful, listing individual package names.

- Each package referenced in VuXML now has its own index page linked
  from the package name page, e.g. pkg-squid.html.  The index page lists
  all entries affecting that package.  In the case of FreeBSD, a link to
  FreshPorts.org is also displayed.

- For entries which contain a CVE name reference, one may "hover" the
  mouse over the CVE name to get a pop-up description of the CVE as
  provided by MITRE.

- Each CVE name referenced in VuXML now has its own index page, e.g.
  cveitem-2004-1308.html and cveitem-2000-0442.html.  Those pages
  contents are generated directly from MITRE's CVE list.

Cheers,
