Maintainence update, Minor improvements to a few things

made sprinklers accessible. scientist starts with one.

thalassophobia update? what? huh? you saw nothing. (minor campaign fixes.)

tweaked loot tables. you can no longer fabricate glow crystals (you can make the appropriately named synthetic ones though), and crystals spawn less frequently (wrecks should hypothetically no longer be crystal surplus candybags)

tied up some loose ends:
-scientist has a new plant. this will be the last plant that the scientist has starting access to and is the penultimate alien plant. the focus will now be completely on earth-plants.
-fixed campaign so some of the dialogue is less shitty/vague/wordy and also made the starting selection text more clear. will try to replace this whole part with a vote eventually.
-fixed issue where start of capmaign softlocked if let me choose was on and allowed you to not have a captain.
-made the UC look less like dogshit. still needs work though.

hopefully next up:
-few more chemicals, possibly chemtron9000?
-earth plants, although their implementation is going to be kinda hard/wonky because of the way plants work.

Fixed the fumigator light not showing up for nitrous oxide and made the light more visible (albiet more shitty looking).

Significant expansions/improvements to existing gasses:
-Gas cylinders can now be thrown. If they hit a surface hard enough they can rupture and spawn a cloud of gas that gives a concentrated dose to bypassers. Obviously this destroys the canister.
-The fumigator has a color coded light on it indicative of what kind of gas is currently loaded so victims can better know what their sprayers intentions are. Basically, if it's blue/green it's generally good and if it's red or yellowish it's bad.
Also changed up the black hole sounds a little bit. Will probably attempt to fix the pathetic black hole suction soon.

Added "Phoenix Syringe" that can be made in UC

Introduced Universal Constructors and their respective schematics, making access to higher level science stuff easier.

Reverted maggot affliction to its old self, made glowsabers no longer cut through doors (due to lag issues), made bomb collars their own proper sprites and improved beeping
