3 mm receiver under remote control

The 3 mm SIS receiver is now remotely tuned from the control room. This makes tuning much faster, it takes about 6 minutes to change the frequency (without measuring the image sideband rejection). The tuning range has been expanded at the lower end: sky frequencies can now be tuned from 81 GHz to 115.3 GHz.
