Configuration Refactor

[Diyagi]

The way the current configuration works makes code maintenance and feature implementation confusing, when adding an new config you have to edit 200+ lines just to implement the bool for that config.

The goal of this refactor is to make the configuration a bit cleaner and easier to work with, also to de-clutter the Overlay cpp/header a bit.

• Moves all configuration related logic to its own file.
• Removes the default vars, the default value is now the values that the current vars are initialized with.
• Implements an function that saves all vars, this function can be called without the need to pass arguments to it.
• Implements an version field in the JSON file in case migrations of that config file are needed in the future.
• Changes vars that enable/disable ESP actors to pointers that points to its respective array element.
• Changes how Loads are handled so it happens just once, and not every draw call.
• Maybe more, i forgot ,-,

I will leave this as an draft for now so we can work on it, plus this needs more testing.

Config is actively being recoded from the ground up! I'll take a look at this though and make any changes required moving forward! <3
