- fix not being able to burn things after turning the knob

Not sure what exactly changed, but turning the knob lead to the nozzle being blocked by "something", so I'm guessing an update broke behaviour of raycasting from inside a voxel in some cases.

fix: nozzle keybind defaults not being set correctly if no options haven't been opened yet

feat: improve particles
feat: adjust light colors

feat: add option to set the inventory slot
fix: some options menu quirk, also removed the non-functioning debug toggle

fix: some unnecessary function calls

fix: flame particles sticking to surfaces which sometimes introduced dissimilarities with simulated particles
chore: improve parts of the code base

fix: options resetting when reentering options screen
performance: improve performance by removing unnecessary particles

fix: mod not working after reload

Apparently the "#include" syntax does not work after reloads, so i had to implement a workaround.
Sorry for the inconvenience!
