Add a new package SKK, Simple Kana to Kanji conversion program.
This package replaces inputmethod/ddskk program; the DISTNAME still has
the prefix `dd' (which stands for daredevil), but it is the official
successor of the original SKK-9.6 developed by Mr.Masahiko Sato, and
the release is announced under the name of SKK.  So we decided to 
change the package name.

Notable changes from ddskk-20030629 include: enhancements to skk-study,
bug fixes, support of ML dictionary, etc.
