Allow to work without ethernet

This patch allows both the arduino itself, and the MATLAB interface, to work with no ethernet connection, using USB-serial only.

This is controlled by a flag NO_ETHERNET in 4DrobotServer_config.h.

Testing that this doesn't actually break ethernet functionality, and that it works correctly, is needed.

Tested(ish), seems to work fine :) Both with and without hardware, and with serial when also connected to ethernet.
