Some devices do not support short reports and thus have a quirk (HIDPP_QUIRK_MISSING_SHORT_REPORTS) that forces short reports to be sent as long reports. Since all Bluetooth LE HID++ devices seem to act this way, HIDPP_QUIRK_CLASS_BLUETOOTH_LE aliases this quirk. To allow for some space for future quirks, I changed the comment that defines the bits reserved for classes from 2...20 to 2..15.
