Release 0.4.2

Final stability fixes after 0.4.1: Model Error leaves out spans with
unknown inputs; window sensors unknown at startup stay unknown, with last
known states restored as unknown across restarts; unload, reload and
removal can no longer publish stale results or recreate a deleted model;
Forecast Error scores only forecasts whose plan the relay matched within
2 minutes. Adds Reset learned model to Configure. Still observation-only.
