Fixes current_cycle being incremented twice for certain reagents.
Fixes flash never working for /datum/effect/effect/system/reagents_explosion because of a typo.
Readding nitroglycerin reagent, it can now be stabilized with stabilizing agent and can explodes when exposed to 474K (like blackpowder).
Readjusted black powder explosion: no more flash (like nitroglycerin), tweaked the values a bit to not nerf blackpowder explosion.
Adding changelog.
All reagents are back to being metabolized every tick. I adjusted the goon chem so their effects aren't changed too much.
Removing some probability and randomness from goon chem effects to make it more predictable.
Adding overdose to space drug.
Making a drug reagent category.
Changed check_ear_prot() for carbons: alien are now immune, and monkey checks their head for ear protection.
Changed flashpowder flashing code and blackpowder explosion code to use already existing procs.
Moved chemical_mob_spawn and goon_vortex procs to /datum/chemical_reaction/
Fixes double overdose message for sugar.
Remove the "if(!M) M = holder.my_atom" at the beginning of a lot of on_mob_life procs, you already can't call on_mob_life if M is null
(Chemistry-Holder.dm).
Moved random_color_list to datum/reagent/colorful_reagent
Nerfed healing power of stimulant. Buffed ephedrine a bit.
Fixes some goon chem on_reaction() proc leaving resulting chem behind when they shouldn't.
Removes Life, nitroglycerin and Corgium reagents. They're now only a chemical reaction.
Moved grenade launcher and syringe gun from reagents module folder to gun folder.
Added a message for the ghost when someone is trying to revive its corpse with strange reagent. (like defib)
Fixes Frost oil and other consumable reagents using current_cycle var.
Fixes runtime where during metabolization a reagent removes another then the latter still calls on_mob_life().
obj/effect/effect all pool themselves.
PoolOrNew() can now be passed a type and a list instead of a type and a location. In that case, the list will be passed to New() via arglist().
RCD's now delete their spark system and properly garbage collect.
