Ported Basic Overmap Functionality

- Ports the overmap, ships, sectors, and "landable" ships from baystation.
- Ports necessary computers to control ships and overmap shuttles.
- Shims missing machine and computer functionality pending future enhancements.
- Includes required new sprites and sounds.
