wip/sailor 0.2.20160211 NetBSD

Sailor is based on chroot and pkgin, it will create a chrooted environment containing only the needed pieces in order to install and / or run a service. Note that sailor's goal is not to provide bullet-proof security, chroot is definitely not a trustable isolator; instead, sailor is a really convenient way of trying / testing an evironment without compromising your workstation filesystem.
