Updating voltage parameter (CURR->BAT)

Hi. Still lovin’ Maverick. I was trying to figure out why for a new flyer Maverick is showing NO DATA for the three voltage and current items – I know that voltage is going into the Dataflash. I just realized that voltage used to be CURR.volt but apparently in ArduCopter 3.6 was renamed to BAT.volt. The other CURR. items were probably similarly changed, though I have not verified that. Would it be difficult for Maverick to be updated to handle both the CURR. and BAT. forms? Thanks!
