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.
* Optimized garbage collection of radiation sources until we get qdel() hints.
* Made the RADIATION_LOWER_LIMIT configurable (option for people to save some cpu time)
* Added some comments and broke the proccessor into separate procs for profiling purposes
* Added a changelog.
Adds some 'plain' goggles that are airtight, and as such protect your eyes from things like phoron. Also allows eyewear to protect you from phoron if it's airtight (and hiding your eyes). Added airtight flag to science goggles, welding goggles, and 'plain' goggles I added. Weldning goggles only protect your eyes when down, since it removes the covers eyes flag when up.
s = Speedloaders. (Functionally the same as clips, but they're not
_really_ the same thing, just in case we change these later.)
c = Clips. (Can also be used to fill other magazines.)
m = Magazine. (Holds ammo rounds.)
a = Ammo. (Individual rounds of ammo.)
* The performance of the radiation controller as-is was not fast enough for inclusion in production servers, but it has some nice featuers, so rewrote it to be more performant.
* Instead of storing the radiation strength for every turf, we only store the sources of radiation, and calculate the strength only for mobs who might be in range.
* Old method was ray-tracing to every turf in range whether anything was there to be irradiated or not. Could be hundreds of turfs. New method only lazily calcualtes strength at a turf if we actually need to know it. Often times this is zero turfs if nobody is standing in engineering.
* Removed the automatic processing of objects with "rad_power" set. Objects are responsible for calling the repository to create/update their radiation sources. Saves some extra overhead that in practice was redundant with other process controllers.
* Also tweaked to be more respectful of qdel'd objects and added some comments.
