* Polaris initial plane upstream merge
* POLARIS: Fix RIG visors with new plane system, and material scanner VIS_FULLBRIGHT
* POLARIS: Fix GetFlatIcon so that cameras and id pictures don't show the HUD overlays.
* POLARIS: Adds a 'alter values' proc for plane master ease of tweaking
Setting stuff like colorblindness variety and things.
* Remove NIF reference, fix lighting layer define
* Handle effects above lighting plane
* Moved all layer defines to planes+layers.dm
* Fixed overlays that are supposed to be above lighting to use the PLANE_LIGHTING_ABOVE
* Merge: 3000% human/update_icons() speed improvement
* Merge: Avoid ghosts pointing at things
The current code does not account for there ever being more than one holodeck. This alters it so that you can make various subtypes of the holodeck computer for other areas, each with different loadable programs.
Links many map-specific details such as the station name, z-level information, and allowed jobs from global vars to map datum vars, which should help us maintain multiple maps at once in the future, which will be needed for the future Southern Cross.
Note that a config change will be needed to change GENERATE_ASTEROID to GENERATE_MAP, otherwise no changes should be required to continue normal map usage.
To change to a different map, it's suggested to tick the file that ticks all the other needed files, which for the Northern Star is called northern_star.dm.
Now possible to use items other than emags on holodeck computers
Blobs no longer make computers lose their density state.
Holodeck computers can now be repaired (and built, but since they cannot be configured they'll be useless).
Fixes#11263.
Remains of player blob axed.
blob_act() axed. Blob now has an arbitary set of things it can attack.
It will flow over everything else. Blob has an awful tendency to destroy
non-craftables.
Will test more tomorrow.
Blob will now attack mechs.
Fixes#8106.
Fixes#10705.
Computers now use an overlay based system, instead of demanding a full set of icons (on, off, broken) for every different computer.
Partially ports ParadiseSS13/Paradise#1468 which is a port of tgstation/-tg-station#9931.
Merges the two meteor events into one, and now takes severity into consideration instead.
Including the basic meteors there are also new types ranging from flaming to radioactive which may drop appropriate types of ore.
