Subject: [PATCH] Added Warning Cell Voltage Added Warning Cell Voltage to
 Battery voltage in Configuration tab. When battery has deployed to level that
 is defined with warning cell voltage buzzer starts slow beeping and copter
 can still land safely. When min voltage is reached beeper start fast
 "screaming" and LIPO is empty (to point when it could be damaged from over
 discharging if using that default 3.3V).
