Connect both definitions of verbosity
Connect both definitions of verbosity

dials.* programs have two separate definitions of verbosity, one defined
in the traditional UNIX manner of adding '-v' to the command line,
another via a PHIL parameter:

$ dials.import --help | grep verbos
  -v                    Increase verbosity
$ dials.import -c 0 | grep verbos
verbosity = 1

One did not influence the other, so any output produced could follow
either definition which may be surprising for the user.
