Expand options with dublin-core official categories

[atla5]

add in some more of the dublin-core elements with their associated refinements/qualifiers to allow for more specific and expansive cataloging control without having to go into the code.

maintain hierarchy for advanced readability and to allow the user to forego specificity for the learning curve if desired.

rationale:

• the config/shared bit is the part of using the program that was always meant/allowed to be more technical. expanding this doesn't compromise usability or learnability either, especially given hierarchy
• will help to extend the quality of metadata attainable by the program.

[atla5]

consider adding in more commonly phrased versions of the same thing for student workers/catalogers.

these shortcut/nickname words would just be translated to the other at parse-time.

(e.g. "RELATION_ISPARTOFSERIES" <-> "SERIES")

[atla5]

leaving out the extra/redundant nicknames and preferring fidelity to the dc system. at least for a while.

dc's hierarchy (with limited first order items) isn't too hard to learn, and the config section determination can (and likely) will be assisted by an advisor who knows the classifications anyway.
