A few additional enhancements

I'm still chugging along decoding the settings in HID feature report 0xB (11) and managed to decipher a few more items from the user interface section of settings:
* language
* temperature units
* flow units
* pressure units
* decimal separator
* info pages (still incomplete)

I haven't managed to identify all of the info page values yet, but the code will work as-is (unsupported info pages will just be referenced as unknown). I will be posting additional updates as more are identified.
