Leshana 0a461a507b Fix sector initialization stack overflow crash.
- Replace changes from 8c7371c5d4b900308cecdba5335989e8c9f191fe
    - Removed debugging prints in skybox generation
    - Reverted change to GetConnnectedZLevels to avoid the chicken-or-egg initialization issue of find_z_levels() requiring knowledge of a sector's z-levels during the attempt to determine a sector's z-levels.
    - Make find_z_levels() always called again so that lazy open space initialization works on landable ships again.
- Instead, allow static configuration of sector map_z to override the default behavior of calling GetConnectedZLevels()
