  1. Change CapacityMode from 2 (%) to 1 (mWh) 

    This fixes abratchik#11 by also reporting battery capacity percentage on Windows laptops that already has a battery. This makes the sample more interesting to demonstrate.

The `CapacityMode` units are documented in [Usage Tables for HID Power Devices](https://www.usb.org/sites/default/files/pdcv11.pdf) section 4.2.3 Battery Controls.

The total battery charge % reported by Windows appear to be a weighted sum of each battery, weighted by their respective capacities. The Arduino battery is currently harcoded to `iFullChargeCapacity = 100` mWh, which is quite small. It does therefore have a relatively low influence on the total battery charge % on the laptop I've tested on.
