Open Route 29 and Cherrygrove City

- Enable Route 29, its Route 46 gate, Cherrygrove City and its buildings.
- Run item balls through FindItemInBallScript and fruit trees through
  FruitTreeScript, with a native daily reset of the daily engine flags.
- Port the Pokémon Center nurse (HealParty with the PP Up clamp,
  CheckPokerus, phone-call checks) and record the whiteout spawn on
  entering a Pokémon Center, as EnterMapWarp does.
- Port standard Poké Marts with keyboard, D-pad and pointer menus.
- Add the recoil battle command (Struggle) and VAR_BOXSPACE.
- Save fruit trees, the daily reset day and the last spawn map; older
  version-3 backups migrate by absence.
