Update to 2.4:
In fact very little has changed in V2.4.  A few bugs were fixed, and one
new feature, namely the display of multiple results in a
multi-dictionary lookup, was added. One bug-fix was to re-instate a
feature that was accidently dropped out in the V2.2 -> V2.3 update.
(Only one user noticed....)

Pkgsrc change: depend on new edict and kanjidic packages instead of
including a copy of the files.
