Enhance Windows FTDI Driver detection

[PropGit]

Relates to Issue #37.

Attempt to either using DevCon.exe, or create a SetupAPI-based .exe, that can detect the presence (or lack of) the FTDI USB Drivers regardless of whether or not a qualifying USB device has ever been connected to the Windows computer (that session or ever). NOTE: The driver site in the driver store, ready to be attached to a USB device, before the first device is connected. Perhaps that's also the state the driver is in at the start of each session before a USB device is connected.
