Support User values #648
Description
Some things that are possible, not mutually exclusive, not ordered in any manner:
- Add "MediaWiki page" property type #649
- New dedicated "User" property type. Knows about MediaWiki users in UI and validation. Perhaps integrates with profile extensions to give optional user icons like what Notion/Coda/many have. Could have domain-specific constraints like permissions (i.e. Values for your "Curator" property could be limited to those with the "curator" permission). Might make sense as a mini-extension.
- Nothing new. Just create Subjects for users and then use the Relation property type. Because those Subjects would all have the same schema (i.e. WikiUser), the editing UI would only autocomplete on and allow those Subjects
