Moved disco-ball to universe, added functions necessary for fetching, templating, and executing a given disco ball. Made all existing scripts aware of NOOP and how to change their DISCOROOT accordingly. Added skeleton restricted.d/* files for a semi-safe base system. Added disco-param that allows management of parameters on the client (currently isn't smart enough to manage them on the server, or per-module). Added client/bin/disco that actually allows the entire thing to come together and get executed. Still lots of bugs to work out.
