can use the "new" auto* build system decoupled from mozilla build system.
mail/enigmail,-main will replace mail/thunderbird,-enigmail (and
respectively, mail/enigmail,-seamonkey will replace
www/seamonkey,-enigmail) now that i've finally figured out how to
install systemwide extensions in ${LOCALBASE}/lib/mozilla/extensions/${APPID}
and how to automagically enable them.
Finally, we only build enigmail once...
