New AMBEserver Install Process on Github

A new install process for both end users and image builders can be found at ambeserver-install on Github.

This install is simple and straightforward.  It builds and installs a fresh copy of AMBEserver.  It will also add a new file descriptor /dev/ThumbDV when your ThumbDV™ is plugged into a USB port. Programs, including AMBEserver can then find the ThumbDV™ regardless of any other /dev/ttyUSBx devices you may have installed.

Systemd service files and ambeserver configuration files are also provided.
