New sensors.conf keyword 'ignore'

This often-asked for, long-planned and somewhat-forgotten feature
makes it possible to tell libsensors-linked applications (like
the sensors program) that certain features should not be displayed.
This is very nice for things like unconnected temperature sensors
or fans.

Modifications to the library code, to the sensors program and to
the documentation and example sensors.conf file.
