thunderbird 6.0 lightning needs updating

The file for the lightning xpi is out of date,
/usr/ports/mail/thunderbird/work/comm-release/calendar/lightning#less 
install.rdf
The maxVersion5.* needs to updated to work with the new Thunderbird 6.0.

I'm unsure the correct way to do this (Mozilla and/or FreeBSD) version 
bump, but the "cheap hack" is just changing the 5.* to 6
  (or any higher number)
