Journal all the things

[ben]

This is a rough proof-of-concept for the idea outlined in https://github.com/ben/foundry-ironsworn/issues/386#issuecomment-1152949360. The idea is that all the data that's currently stored in progress item data is now stored in flags on a journal entry. There's a new Actor type (jenpc) and a new Item type (jeprogress) that only contain journal-entry IDs for reference.

• [x] Add new types to template.json
• [x] Hack together a journal-entry sidebar and a button to open it
  • [x] Some settings that work properly
  • [x] Buttons to generate actor/item
  • [x] If actor and/or item exist, links to drag them around
  • [ ] Image control which syncs to the linked actor/item
  • [ ] Sync name to actor/item
• [ ] jenpc actor
  • [ ] Trying to open its sheet instead opens the journal entry
• [ ] jeprogress item
  • [ ] Trying to open its sheet instead opens the journal entry
  • [ ] Support in character sheets for this type of item
• [ ] Update CHANGELOG.md
