Update reprocessing options

[ehenneken]

Of all reprocessing options currently available, only the score and fail ones make sense. The bibstem and year options refer to entries in the bibcode column in the resolved_references table. This does not correspond to any conceivable use case. Instead, we need reprocess options for the following use cases:

1. Reprocess all references for a particular journal
2. Reprocess all references for a particular volume of a particular journal
3. Reprocess all references for a particular publication

It is conceivable that we may update a particular parser as some point. If that ever happens, we may want to reprocess all references that were processed by this parser:

4. Reprocess all references that correspond to a particular parser

This topic merits a discussion.
