Port the Pokédex list, entries and tab (#35)

The start menu's POKéDEX runs Pokedex in New mode: the list up to the
last seen Pokémon, its cursor and page moves, and DisplayDexEntry with
the category, number, footprint, and the height, weight and pages once
caught. The Pokédex tab shows the same records from the loaded game.
Order, entries and footprints are compared with the pinned PRET source.

AREA, CRY, PRNT, the option and search screens, Old and A to Z modes
and Unown mode remain.
