- Replace changes from 8c7371c5d4
- 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()
- Set initialized = FALSE on unsimulated turfs that need to intialize.
- Most of area/New() to initialize
- Faster lookup of self-init on atoms
- Split air alarm and fire alarm files, move new to initialize
- Tweak decals and opacity

- Port based on Baystation's implementation and customized for our code and usages.
- Switched space icon_state permutation to a "dust" overlay that is permutated the same way. As an overlay, the dust can be *above* the parallax planes. Space turfs are now white to allow skybox to BLEND_MULTIPLY onto them.
- Added skybox hud effect that replaces background space turfs with an image moved to create a parallax effect.
- Added skybox subsystem to generate and manage skybox parallax images, and lots of images for it!
