_ pobox-1.2.6 enhance patch

Orginal pbserver can answer max 40 words in one query. This patch makes pbserver to be able to answer max 256 words.

And This patch also makes pbserver to be able to save learndic when accept signal(INT, TERM).

_ ノートPCのバッテリー残量が少なくなったら自動的にサスペンドするためのACPI設定方法

/etc/acpi/acpi_handler.sh

バッテリーに関するイベントを検知したらスクリプト(/etc/acpi/lowbattery.sh)を起動する。

バッテリー駆動の間は60秒間隔でバッテリー残量をチェックし、残量が10%を切った場合サスペンドする。ACアダプタ駆動になったら終了する。
