Move www/horde-devel -> www/horde2 & mail/imp-devel -> mail/imp3
From PR's description:
IMP 3.0 is the stable release of IMP,
and Horde 2.0 the stable release of Horde.
Note: mail/imp3 and deskutils/kronolith are marked as IS_INTERACTIVE
since they need depending port mod_php4 with its mcrypt option
enabled by hand.
