Allow editing the mod configuration

[AlyxMoon]

User should be able to view the available settings that are configured for a mod, and edit these settings. There should be two options for saving:

• Have that configuration be saved for the mod so that it exists as the default settings
• The configuration will only be active for the specified profiles

One major step to this is figuring out how the mod-settings.dat is encoded and how to read/write correctly to it so the game can parse it.
