G4KLX software updates

Jonathan Naylor (G4KLX) has updated his D-Star software, I hadn't looked in some time, but there are a good few updates. So today I have re-compiled the code runing on Pi-Star to the latest versions. There are some changes - sadly the config programs are GUI only, and I had to run those in order to add the aditional lines for the new DV-MEGA code.

The other side effect is that the "admin portal" also needed to be updated to include the same configuration updates, but that was trivial thankfully.

The remaining project is to make copying the SD-Card in situe possible form the admin console.
