Add the Johto and Kanto atlas to the Map tab

The Map tab draws the region's Town Map from the ROM with the player's
landmark, the visited flypoints as Fly destinations and the landmarks
whose maps are ported. Kanto opens with the Fly map's Indigo Plateau
rule. Landmark positions and flypoints are compared with the pinned
PRET source.

Closes #36
