* Port of the "Airflow" portions of Yonaguni/EuropaStation#618
* The "airflow" part of ZAS used to be handled by a sleep'd loop. This has the potential to bunch up and lag. Switching to a StonedMC managed subsystem improves it.
* Fixed to ensure that zshadow mobs cannot be blown around by the wind no matter how fierce.
* Added a message to mobs informing them when their boots save them from being wind-thwapped.
* Check w_class on non-item objects if they have it defined (might as well since var/w_class is on /obj)
* Tiny optimization of c_airblock
* Creates the SSair subsystem which replaces the Setup, Start(), and Tick() procs of air_master.
* It may be best to have SSair completely replace air_master, but for now we are having them work together. It does completely replace the old processScheduer air ticker however.
* Remove the obsolete Setup and Tick procs.
* Adjust admin and debug verbs that dealt with some ZAS internals to work with the new implementation.
* Adds "typecache" utility functions. A fast way to filter lists by type.
Ported from TG
* Ports the "orbit" feature and subsystem from TG
* Adds a feature that allows mobs and objs to "orbit" around some atom. They literally are moved around in circles. See the `orbit` proc in orbit.dm.
* Adds a subsystem that processes the actual movement of orbiting items.
* Adds utility methods for common machinery behavior.
* Adds default_unfasten_wrench which handles the standard anchor/unanchor behavior of wrenches being used on machines. Together with the other default_x_tool machinery procs we can eliminate having that code duplicated in dozens of places!
* Adds is_wire_tool proc to easily detect when a machine is hit with a tool that should open its wires UI (if it has one).
Based on ideas from Paradise, with improvements for us.
* Implements the Tesla Engine
Ported from a mixture of TG and Paradise code and assets: Edison's Bane
Includes the tesla energy ball itself, the generator that makes it, tesla coils, grounding rods, the circuits and frames to build them.
* Switch dusting to zapping on impact and spin better
Ported /tg SpinAnimation which supports more than triangles.
* This is PHASE 1 of a multi-phase conversion. In this first phase we implement the subsystem, but leave it processing the existing global list variables. In the next phase we will switch to use datum variables in the subsystem. The main reason for splitting into two phases is ease of code review; change the meaningful code without the hundreds of machines -> SSmachines.machinery substitutions.
* We did declare macros for adding/removing things to the processing lists, and convert everywhere to use the macros.
* Added var/is_processing to /datum to keep track of whether an instance is already in a processing list (prevents it being in the list twice!) and also debugging, making sure its not in two lists etc.
* NOTE: The global machines list is **no longer sorted** for performance reasons. As far as I know, the only module that actually ever cared was cameras. Our camera system already handles its own sorting in the cameranets anyway, so it should no longer be needed.
* Adds defines for world.tick_usage
* This provides no useful benefit whatsoever, but /tg and Baystation12 have done it, so it will make porting future code easier if we do too. No real harm done either.
Requires mid-round var edit to enable, can be used to determine how much of each tick each mob's Life call uses. Will not tell you WHY, of course, but will aim you at a specific mob hopefully. Worst case, we find out that it's actually just every mob.
Mostly ports /tg/'s method of seeding submaps into specific z-levels.
Due to the low number of submaps present, all of the PoIs are guaranteed to spawn. As more are added, this should fix itself.
-Adds a nifsoft that can be used for manual mind backups on the go sleevemate style.
-Fixes one-time backups not saving nifs (sleevemate and this thing)
-Apparently the backup proc only saved nifs on the second sync.
New lighting system is needed to handle updating literally 14k+ tiles whenever the sun moves. The straight port seems to have had no adverse effects from what I could see. Don't know if it's more performant but it doesn't seem to be less.
I didn't expect the latter would be needed for the former.
* No changes to lighting logic at all, it still processes sources, corners, and overlays in that order.
* Also optimized the initial creation of lighting overlays, and made it include CHECK_TICKs
* Removed the statistics gathering, at least for now.
* Since the transcore has a ticker process, it really should be a subsystem. Converted it over. However, because its ticker is so fast, I did not bother implementing MC_TICK_CHECK into it. Therefore it has the SS_NO_TICK_CHECK flag.
* Because its a subsystem, the global variable is now SStranscore instead of transcore.
* Because subsystems are so easy to debug, I removed the "TC" debugging variable from the machines that used it.
* Organized a few files. The transcore subsystem is in the subsystems folder. Defines had to be moved to defines folder so they are included first.
* Based on https://github.com/tgstation/tgstation/pull/25386
* Create macro for defining new subsystem types.
* Create PreInit proc to handle setup that needs to be done before the map loads
* Rename garbage_controller subsystem to garbage so it matches its global SSgarbage variable name.
