mailest 0.9.4

[YASUOKA Masahiko]

Hi,

I wrote programs named "mailest" which can be used as a search backend
of Mew using "Hyper Estrairer". It can replace existing "mewest".

"mailest" is fast. The implementation became bigger than I'd
expected, but it's still light (not consume CPU or I/O resource so
much).

Enjoy!
