Feature Add: Loading/Swapping Media & Prompt DBs

[rmusser01]

Title.

As a user, I would like to be able to have specific mediaDBs for specific fields/areas of research.
So that I may be able to load a DB for Biology, and have a separate DB for astronomy.
While this is doable/can be done through tagging/meta-tags, given the expected growth in size of DBs, it would make sense to be able to 'archive' DBs after a project or goal completion, and then be able to 'restore' or examine the contents of said DB, with the expectation that no changes to the data has occurred.

Also would be handy for swapping research DBs with other individuals.
Ditto for prompts.
