Port Fly, Dig, Teleport and the Escape Rope

FLY opens _FlyMap in the party menu: the region's Town Map with "Where?",
the visited flypoints in turn and the Fly user's icon, then FlyScript flies
the icon off along SpriteAnimFunc_FlyFrom's path, enters the spawn point and
lands it with SpriteAnimFunc_FlyTo. Teleport returns to the last Pokémon
Center's town through IsSpawnPoint. Dig and the Escape Rope lead out of a
cave to the warp EnterMapWarp's SaveDigWarp recorded, which saves now keep.

newloadmap stops its script as StopScript does and the world resumes it on
the new map, which the landing and return movements need. A destination
that is not ported yet gives a notice.

Closes #25
