WIP - Captive

Some technical detail on how the map is constructed.

• Each base has an outside and an inside map, each is a grid of 64x32 squares (length x height).
• The maps have an upper-left origin.
• Like in a lot of old games, when you go up or down a level on the inside map, you are actually only jumping between different parts of the same level/map, verticality is just technical trickery.
