The current implementation uses "wacom_battery" as a generic name for
batteries. This prevents us to have two Wacom devices with a battery
attached as the power system will complain about the name which is already
registered.
Use a specific name for each type of battery attached.
A bug in upower prevents us to use spaces in the power name, so replace
each space by '_'.
