Add option to disable certain mods via JSON

[ithinkandicode]

We could add support for checking a file called mods.json in the user data folder, and when ModLoader inits, we could check that file and skip any disabled mods.

We could also provide a func to save the settings to this file.

This would let games implement a toggle to enable/disable certain mods from within the game itself, so users don't need to unsubscribe from them in the workshop/Thunderstore, or manually delete/rename mod ZIPs from their game folder.

agree. we can salvage a bit from #33 - mod_loader and mod_loader_helper, but just saving to a json instead.

Maybe we can add some simple profile functionality with this?

mods-[profileName].json

I play on PC and Steam Deck and Workshop syncs everything but you might want different mods per system.

I think there is mod pack support in steam workshop?
So maybe there is a way to handle this outside the ModLoader.

I mean that is why I use thunderstore, you have separate profiles, don't think steam has that

[ithinkandicode]

mods-[profileName].json

Best to keep it in one file. Then you can handle load/save with a single read/write operation. Eg:

{
	"current_profile": "Default",
	"profiles": {
		"Default": {
			"Author-ModName": true,
			"Darkly77-ContentLoader": false,
		}
	}
}

Funcs we'll need to provide:

func _load_mod_options() # private, loads options into ModLoader singleton's data on ModLoader init
func save_mod_options() # public, saves all data that's currently in memory, needs to be run after the following 2 funcs too

func enable_mod(mod_id: String, profile: String = "Default")
func disable_mod(mod_id: String, profile: String = "Default")

func create_mod_options_profile(profile: String) # public
func change_mod_options_profile(profile: String) # public

Yes those are good. Should we enable any dependency of a mod when it is enabled? And disable mods if they depend on a mod that is being disabled?

I'm assigning myself to this as I'll be working with JSON saving for the Config JSON issues
