All fixes discussed at the last meeting have been implemented, and the
X-axis labels are now displaying properly.

* Add error messages when required configuration fields are not provided.

* Correct one spelling error in config "Dispaly" -> "Display"

> (2) Enhancement to support calculated values as well as sensor data values.

Decided to go with one merged gadget.

* Add to Data Display menu the calcuated data types: Power Consumed,
Power Generated.

* Stale data threshold will continue to work even for virtual sources
because get latest sensor data works for virtual sources.

* Need a sampling interval field to indicate how frequently to sample
for calculated data. Ignored for sensor data, and must be smaller than
the Display Interval.

* Provide helpful error message if user tries to display sensor data
for a virtual source, recommend switching to calculated data.
