Implementation missing for battery_0_soc and battery_0_volt

[hamishwillee]

There is no implementation for battery_0_soc and battery_0_volt. Please provide implementation and information about what parameters these map to on ardupilot (basically I need to know their "meaning" and possible values and units - so for example "Remaining capacity of the first battery in X units"

It is possible for a UAV to have multiple batteries, and two are specified in the parameters. This implies that there should actually be multiple values for these, or a way to index them.

I verified the lack of these parameters by inspection and testing. To test, I added the following lines to small_demo.py:

print "battery_0_soc: %s" % v.battery_0_soc
print "battery_0_volt: %s" % v.battery_0_volt

And got the exception:

Exception in APIThread-2: 'MPVehicle' object has no attribute 'battery_0_soc'

Closing as this is dealt with by #101 and #102.
