Subject: [feature] privileged bitmask helper

This is still quite untested, and a bit hacky, but the main idea behind
let us have a daemonized bitmask helper, that should be installed by the
Bitmask installer. Its responsibilities are to launch the vpn process as
a privileged user, and start/stop the firewall.
