Displays device battery voltage

Voltage Widget can display battery voltage as a value in mV with modifiable text size and color configured by user.

Sometimes state of charge estimation algorithms have problems with current battery level estimation (because of battery aging, environment temperature jumps, etc.). To have some reference on available charge level user can take into account current battery voltage state.

The app has next peculiarities:

1. Last configuration of text size and color will be applied to all widget instances

2. On some devices Android system provides voltage in volts instead of millivolts, so this app will be useless to determine this parameter
