Bug 2060: Update command line MARC import scripts

Expose authority import functionality to the command line import
scripts, and rename them from commit_biblios_file.pl and
stage_biblios_file.pl to commit_file.pl and stage_file.pl.

To test (note that these instructions assume you have a MARC21
installation and are using the provided sample file):
1. Find a file of authorities (a sample file with MARC21 authorities
   is attached to bug 7475) and download it to your server
2. Stage the file using the following command (replace <filename> with
   the name of the file you saved in step 1):
   > misc/stage_file.pl --file <filename> --authorities
3. Note the batch number the script assigns to your batch
4. Commit the records using the following command (replace <batchnumber>
   with the batch number you made note of in step 3):
   > misc/commit_file.pl --batch-number <batchnumber>
5. Index the authorities Zebraqueue (or wait)
6. Confirm that the new authorities appear.
7. Create a matching rule with the following settings:
   Code: AUTHTEST
   Description: Personal name main entry
   Match threshold: 999
   Record type: Authority record
   Search index: Heading-main
   Score: 1000
   Tag: 100
   Subfields: a
   Offset: 0
   Length: 0
   (note the ID of this matching rule)
8. Stage the authority file again, this time using the following
   command:
   > misc/stage_file.pl --file <filename> --authorities \
     --match <matchingrule>
7. Revert the import with the following command:
   > misc/commit_file.pl --batch-number <batchnumber> --revert
8. Index the authorities Zebraqueue (or wait)
9. Confirm that the records have been removed
10. Import an authority record with the Stage MARC/Manage staged MARC
    tools in exactly the way you would for a bibliographic record,
    but choose "Authority" instead of "Bibliographic" for the record
    type.
