Input: wacom - enhance Wireless Receiver battery reporting
- Reports the current status of the battery (discharging, charging, full).
- Also notify the upower daemon when there is a change in the battery
value.
- keep the battery value as a percentage, not the raw value
- add WACOM_QUIRK_BATTERY to easily add a battery to a device (required
for Bluetooth devices)
