Roadmap to configurability

[acao]

Baseline

• clone airtable schema from discontent mods
• simple & advanced customization docs
• create tags/tag type tables, fields
• custom label for "action" i.e. "event"
• customize texts with airtable

Nice to have

• describe additional field types with configuration mapped to airtable
• i18n/l8n
• alternative backends - graphql (strapi, graphcms, baserow), airtable, faunadb, static git/s3 files
