Title: Airspeed sensor scale

AP_Airspeed: user can now change the airspeed sensor scaling factor, which allows for use of non-standard sensors that cannot be automatically configured (mainly the Honeywell and MEAS ones that all use address 0x28).

Also fixed a minor bug in the I2C code, since previously it would never detect errors with the sensor.
