Shuttles now set themselves up upon being instantiated instead of relying on a monolithic proc in the shuttle controller.
Shuttles can now be defined more cleanly on a per-map basis, as well.
Accidentally fixes a broken admin shuttle.
* The vast majority of gas mixtures never use their `graphic` list. Prime candidate for making a lazy init list.
* While we are here, add nullchecks to ZAS's use of the graphic list a bit. /turf/update_graphics was technically already null safe, but its even better to not bother calling it at all right?
* Initializing a list in the type definition (of any type) incurs a hidden proc call ("init"). Simply by moving the init of the lists to /New() we speed up creation of /datum/gas_mixtures (which happens *often*)
* The list variables still get initialized by the time the instance is created, so this has zero impact on other code, its just starightup faster with no downsides.
Fixes a line printed about staying close to your patient printed in error, and makes syringes work on laying patients again.
The do_surgery overrides are from a bygone era.
Tested == yes
* /datum/reagents/Destroy() does everything /datum/reagents/delete() does and more, and delete() is called only from /obj/effect/Destroy() which is *itself* redundant with its parent /atom/movable/Destroy()
* Fixes https://github.com/VOREStation/VOREStation/issues/561
* Prevents multi-clicking from doing the construction steps multiple times (spawning multiple jugs, or emptying contents of jug multiplie times).
* Prevents after-attack from transferring reagent from jug to cooler twice when putting a jug on.
Semi-rewrites how surgery failure works. Using an improper surface will call the surgery step's fail proc instead of just doing a melee attack.
Adds 'surgery odds' var to objs, which determines effectiveness. The numbers for operating tables/roller beds/tables remain unchanged from the previous version, however doing it this way makes it cleaner to add new surfaces in the future.
Adds a proc to get a surgery surface.
Also makes burn repair on FBPs more efficent, so that one scorched robot does not take literally all of robotic's wires.
