TownTopia: Additions

New
- No raids where monsters can't spawn: TownTopia already skips raids on Peaceful; now they're also skipped when the doMobSpawning game rule is off, or in dimensions you list in [no_raids] dimensions (e.g. "hub:*" for a hub where another mod stops monsters spawning). A raid already under way there is called off.

Fixed
- Stuck villager rescue now also rescues the Mayor, leaves everyone alone during raids (guards hold their ground), and catches villagers stuck on a route even when TownTopia doesn't show where they're heading.
- /village mine fill only fills open space that has rock above it, so trees on a mountainside are left alone.
- Mine fills, refills and closing-in never fill a space with an item frame, painting, armour stand or other entity in it (no more popped-off tokens).
