As a continuation of #9389
As a bonus, any drugs that mentioned their IRL counterpart in their description now describe their predecessor as ancient, and the new ones as modern. The biggest difference here is just the Antihistamine which was given a full new name. They're similar enough that they'll be recognized (most of them) but different enough for us to call our own and not care what the real medicines are/do since these are our sci-fantasy versions just inspired by them.
Converts reagents to use typepaths instead of IDs.
Centralises reagent spawning in a lot of places to use reagents_to_add instead of a variety of custom methods or initialise overrides.
Adds more bedsheet inhands, because immersion.
Penlight has an inhand now.
Lanterns have new inhands.
Ashtray cigarette extinguish now properly plays the sound.
You can put cigarette butts in cigarette packets
also some more stupid drop sounds
Made it so items get their pixel x/y reset on pickup.
Thrown items now also get their pixel placement slightly randomized.
Tweaked the center of mass on a boatload of items to be more accurate to their sprite art.
Replaced a bunch of randomized pixel placement code into a unifying proc; randpixel_xy() that uses an item's randpixel var.
Refactors objects.dmi and items.dmi
Adds some more uses to glass jar - now you can use it as a tip jar AND a reagent container!
you can also see reagents inside like a beaker
also improves sprites for wrapping paper and the pocketwatch
This basically makes it easier for future sprite improvements
