Release 0.4.1

Stability and correctness after 0.4.0: unknown window states are no longer
read as closed; learned coefficients are reset selectively when the
configuration they were learned under changes; plans are discarded when an
input changed during optimization, and an overtaken run never publishes;
model accuracy (Model Error) is separated from the accuracy of published
forecasts (new Forecast Error sensor). Base coefficients report confidence;
sensor weights are labelled in the zone form. Still observation-only.
