The state of maintenance is now randomly generated.
This includes patches of oil, trash, spiderwebs, dirt, and so forth.
Utilizes a system which makes it possible to apply custom turf initializers per area.
Makes several custom color definitions, utilized by the floor painter, floor tiles, decals, etc.
Colored floor turfs now use a white icon state and applies a color, similar to the corresponding decals. This ensures they have the same color tone (was slightly off previously).
Colored floor tiles also use a white icon state and color application.
Removes now unused item states.
Adds a couple of decals to the Thunderdome.
Rotates sleepers/scanners on z-level 1 and 2. Had already done so for z-level 5. Fixes#11058.
Full tile windows no longer appear to exist? Replaces the glass on the toxin test site with reinforced glass spawners.
Merges the use of the is_small and mob_size into one.
Changes the species size handling to set the mob size instead of being yet another separate var to check.
When a meteor event triggers it now selects a main edge to arrive from, with a 20% probability to come from either neighboring edge. Will never arrive from the opposite edge.
The meteor event end time is now made more useful, and is based on a longest delay between meteor waves scenario.
The meteor event now supports multiple station Z-levels.
Removes the meteor sounds, as they can rarely be heard over the explosions anyway.
Meteors coming from the east would immediately be transfered to another Z-level and deleted, due to being considered outside the Z-level transition border.
At some point a return had snuck in before the mob-push/swap flag settings. I blame a merge.
Relocated that code to handle_post_spawn() to hopefully ensure it'll always fire when appropriate.
This increases the number of meteors which survive to reach the station, as there is some tendency for them to spawn on the same location (but not necessarily fly in the same direction).
