Initial FreeBSD support with pkgng plugin
Add a basic pkgng plugin as a preparation to integrate etckeeper on FreeBSD. Currently not enabled to build automatically. To use on FreeBSD, install etckeeper manually and install the plugin with: $ cd pkgng $ make $ make install and add this line to /usr/local/etc/pkg.conf: PLUGINS [ etckeeper ]
