* Add a new component: currentstateserver - Add a skeleton for it, with databases and a single query method. - Add integration tests for it. - Add listen/address fields in the config (breaking as this will force people to specify this to validate) Not currently hooked up to anything yet. * Unbreak config tests * Add current_state to sample config * comments
