this changes the calibration code to require at least 5 good reads
from the compass during initialisation. The calibration is taken as
the average of the 5 values.
This also fixes the expected values for the 3 axes for the 5883 to
match reality.
We also save a bit of code space by adding a common rotate_for_5883L()
routine.

this adds error checking to all operations on the compass, to ensure
that we don't accept invalid data
This also fixes the calibration values for the 5883L to match the
recommended values in the spec

Most of the compass functionality is now abstracted in a base class, with the various sub-classes implementing just their unique functionality.
