Fixes #3881, #3965, #4070, #4079 (#4181)

Overview
Fixes/Tweaks PRs #3881 , #3965 , #4070 , and #4079.

#3881
Auto-Hiss was really bad. There is now a chance that the Dionaea autohiss will actually fully pronounce a word properly. Words like "everything" and "course" are no longer read as "eeeeveeerthing" or "courseeee".

#3965
Poking people with the cane would sometimes cause an excessive amount of blood, so I just removed the damage altogether poke people at your own leisure now.

#4070
Some garbage items had too high of a chance. Hindsight, it's dumb for an arcade machine to vend alcohol. The red space suit replica is also useless and doesn't work really.

#4079
Burritos used a terrible way of mixing chemicals in recipes, so now they have a proper way of transferring chemicals. Burritos now also require more meat, and by extension, are now more filling.
