Bruce M Simpson e8f6999c1b Add an RC script for saned, and borrow machinery for creating
a dedicated sandbox user account from the nullmailer port.

Also add a pkg-message which describes how to tie down a USB
scanner to this sandbox using devd(8) in FreeBSD 8, as well as
describing what config files likely need editing.
Note: This text probably belongs in the FreeBSD Handbook.

Bump PORTREVISION.
