We now have the ability via @service to list, start, and stop Twisted services. In this case, this just lets us start/stop IMC2 right now. As people write more services to plug in in the future, this may expand.

@service/list will show you the service names. If you see that your IMC has died due to an error, @service/start IMC2 will get it up and running again. I've also added an 'imcstatus' command to show more detailed information about your IMC2 connection.
