oh boy, quite a bit

 - daemonize rubydns server
 - use refcounting to spin up/tear down server automatically
 - kill provisioner; move it into an action
 - remove resov.conf sedding, just use iptables
 - all config is user-local rather than project-local, enabling
   cross-project collaboration
 - ability to control server via commands
 - ability to list dependent vms via command
