Set version number, document USB descriptors

The iSerial descriptor now holds the firmware version number.  This is
1.0.0 since I don't expect any major API changes any time soon.  The USB
descriptors have been documented in docs/console_config.md so there
will be no questions as to how to identify the devices and what their
"serial numbers" mean.
