[sisyphus] ifup-pptp

[Yura Zotov]

Я написал скрипты, которые дают возможность стартовать
PPTP-туннели так же, как и другие сетевые интерфейсы, т.е.

ifup pptp0
ifdown pptp0

соответственно и service network start|stop тоже будет их
запускать/стопить.

Посмотрите, кто заинтересован. Если проблем не будет, я включу
эти скрипты следующую сборку пакета.
