DV3000 / DV3000U Updates

Updated daemons and controls scripts to support the DV3000 (GPIO AMBE
device for Raspberry PI) and DV3000U (USB AMBE device for Linux/Mac OS
X/Cygwin environments.

The Mac OS X version requires an FTDI driver for the USB Serial Port

We should deprecate AMBETools/DV3000 and direct users to
DummyRepeater/DV3000 or elevate DV3000 to its own project.
