Source book datums

[FalloutFalcon]

About The Pull Request

Cool datum we can use to parse out some behavoir based on what book types come from (including displaying such to the end-user so they can look it up themselves)

Why It's Good For The Game

We already like to mark where stuff comes from with comments, why not codify it and let it be used for behavior.

Changelog

🆑
code: new var on datum level for storing info on what source book it comes from
config: Adds config for limiting merit based on official status
