Breed at the Day-Care, hatch Eggs, draw MAIL stationery and browse the Hall of Fame (Closes #29)

- Day-Care and breeding: deposits, withdrawal pricing and growth,
  compatibility, egg species, DVs and moves, DayCareStep, egg
  collection and the Odd Egg, compared with the cartridge's routines.
- CountStep: walking happiness, DoEggStep, DayCareStep and DoBikeStep
  in the original's order; HatchEggs with the ROM's hatch animation,
  compared frame by frame with the original.
- MAIL: all ten stationery types and the Portrait MAIL picture,
  compared with the cartridge's tilemaps, graphics and palettes.
- Printing: Bill's PC boxes, Pokedex PRNT, MAIL and the Photo Studio
  take the original's absent-printer path.
- Hall of Fame records (saved apart from the League flag, ready for the
  League to call) and the Hall of Fame PC, compared with the cartridge's
  _HallOfFamePC on 255 pages.
