[Halld-offline] run-dependent magnetic field settings

[Sean Dobbs]

Hi all,

I've pushed another change so that the programs quit if a magnetic field is
requested from the CCDB and is not found.  A help message is printed in
that case, illustrating options for specifying magnetic fields on the
command line.  The corresponding changes to the CCDB to remove default
magnetic field settings are still ongoing.

Also, note that any other configuration changes related to the magnetic
field (e.g. using the straight line track fitter when there is no magnetic
field) still need to be specified.

Cheers,
Sean
