This patch copies code from marc21_field_003.pl to create marc21_orgcode.pl
for more generic use. Other fields like 040c or 040d should use it too.
Note: The plugin is used for authorities too (003, 040a).
One behaviour change is added: If the corresponding field is already
filled, it will not be overwritten.
In the unit test marc21_orgcode already replaces marc21_field_003.
Test plan:
[1] Attach plugin marc21_orgcode to a field (e.g. 003) and test it in
the MARC editor of Cataloguing or Authorities.
[2] Check if a value is not overwritten any more.
[3] Run unit test t/db_dependent/FrameworkPlugin.t; don't be distracted by
the noisy warnings of marc21_field_007.pl. They will be addressed on
another report.
