Common - Allow turning down music

User Interface
Common - icon + progress bar + epilepsy settings

Logistics

Vehicles

Effects (new category)
Cook-off
Field Rations ?
Fire
Fragmentation Simulation
G-Forces
Nightvision (Equipment ?)
Hit Reactions
Overheating (Weapons ?)

Pointing ?
View Distance Limiter ?

Fan of reducing the number of categories, but, in my opinion:

Would put logistics & cookoff under vehicles

Would keep common as it is (i.e rename user interface to common)

Overheating to weapons for sure

Need a better changelog of what categories are now removed though

[Dystopian]

Still not sure whether this PR fits ACE. No problem with changelog and moving more settings into categories, but I'd like some confirmation that this change is worth it.

It's also worth noting that we can't move many settings into a single category because of performance issues. Some addons already have their own subcategories (e.g. Map Gestures - Colors), so those settings don't seem movable either.
