Setting current sensor offset voltage in APM Mission Planer. #448

Hello

Could you add the possibility to set offset voltage of current sensor  from 
within APM Mission Planner?

I use several different current sensor (offset voltage is between 0 and 2.5V ) 
and this option would be for me and probably for many other user wery useful.

At this time I need to program APM from scratch every time.

I am using the ACS715 hall effect current sensor and I get about 0.6V offset at 
idle. When I connect the current sensor up after calibration, it says I am 
drawing 4.6A. So even though it is not drawing any current, the battery 
capacity continues to fall.

It would be nice to set this value from the AMP Planner. In the latest 
Ardupilot code I see the parameter is called CURR_AMPS_OFFSET in the config.h 
file.
