0.8.4 - Debug Sliders, Colds Settings

I've created a new solution for the debug sliders of the old Scratch and Godot versions, which is so much better than the old "Create a global variable and unique script to manage it on a hard coded slider"

I've exposed some sliders to the debug menu. More will come as I retrofit the code to use the relevant data.

Colds also make a return, accessible in the debug menu.
