reverse-themeを作りました。

emacs theme

私は Emacsの themeは特にしようしておらず、単に 'emacs --reverse'で起動して
オリジナルの色を反転させて使っているのですが、この場合新しいフレームを作った
場合('C-x 5 2'とか 'emacsclient -c'等)、reverseが反映されていないという
問題がありました。なんで themeとして 'emacs --reverse'を実現できるものを
作ってみました。

対象

Emacs 24で導入された themeの枠組みを使っているので、Emacs 24以上が対象です。

いちいち設定するのは面倒くさかったので、color-theme.elの 'color-theme-print'を
使いました。それでダンプした色情報から font-familyとか themeに関係なさそうな
ものを削除しただけです。この方法だったら、color-themeを使って作成されたものでも
新しい themeに適応するのがそんなに難しくないかと思います。
