Add external controlling functionality to InhibitMaster
Karol and Manuel asked if we could add a control message mechanism to InhibitMaster and friends to help cleanly start/stop/initialize/kill the InhibitMaster. Requirement is a one-shot command issued from JCOP that will put InhibitMaster through its paces. I have a prototype working with the FakeSpillInhibit. Likely will add a "status" message state as well.
(I realize that we have a state machine and commander interface and etc. that this would be good to add into, but likely want something quicker and dirtier for now)
