  Log Message:
  -----------
  Allow on, off, yes and no values for booleans

incoming.conf, innfeed.conf and inn-radius.conf were not allowing
these values.  Now homogenize it, and instruct inncheck to globally
allow these values (it previously wrongly reported as an error the
use of these values in other configuration files like storage.conf or
readers.conf).
