Klaas Hoekema de87c5b19b Add shaded area to show when calling for heat (#617) ...

Adds a series to the climate graph to shade the area under the current
temperature line red when the thermostat is calling for heat.

Uses the current temperature because it's guaranteed to be in the right
temperature range for the graph and it should minimize overlap since by
definition when the thermostat is calling for heat the current temp would
be below the target temp.

Uses `steppedArea` because most other series types don't handle
intermittent (i.e. with sections of `null` throughout) data very well.
