Units not being translated in sensor display and EditContainerNode number displays

[matthew-blackman]

@samreid and I found this issue while investigating locale switching. It looks like the units of the sensor measurements and the number display of the EditContainerNode are not translating when the locale is changed.

I checked the translation utility and the iw translator did not localize V or A. They did, however, provide a translation for volts which is properly appearing in the published sim:

@matthew-blackman and I discovered that the value is correct if you use ?locale=iw for example. But it doesn't dynamically recompute when locale is changed at runtime. We are fixing it now....

@matthew-blackman and I addressed all cases we discovered. SeriesAmmeter, Ammeter, Voltmeter and CircuitElementNumberControl units all update correctly under dynamic locale change.
