Added uart support for HUD: the protocol implementation for the HUD has been added. It may be activated by the compile switch ENABLE_HUD_SUPPORT. Because the HUD will not mapped to the three classic o2 value display slots, the sensor data structure has been increased to the max number of devices => all devices may now raise device specific data.
