Fixed XPLAINBridge project not correctly reading the XMEGA's supply voltage when reporting back to the host.
* \section Sec_ChangeLogXXXXXX Version XXXXXX
* <b>New:</b>
* - Added new ADC_DisableChannel() function (thanks to Mich Davis)
+ * - Added new VTARGET_REF_VOLTS and VTARGET_SCALE_FACTOR compile time defines to the AVRISP-MKII programmer project to set
+ * the VTARGET reference voltage and scale factor
*
* <b>Changed:</b>
* - The RingBuff library code has been replaced in the XPLAINBridge, Benito and USBtoSerial projects with an ultra lightweight
* instead of the split write-only command (thanks to Tim Margush)
* - Fixed RNDISEthernet demos crashing when calculating checksums for Ethernet/TCP packets of more than ~500 bytes due to
* an overflow in the checksum calculation loop (thanks to Kevin Malec)
+ * - Fixed XPLAINBridge project not correctly reading the XMEGA's supply voltage when reporting back to the host
