Settings Management

[apachano]

We need a system to load and manage settings. This should:

• Be able to be exposed to the LUA api for lua modules to register new settings + get values for settings
• Store settings (by save or globally? Both?)
• Expose settings to escape menu in a logical fashion
• Server and client should both have settings systems (Use the same one if possible)
• Settings should be editable via a function (EG exposed to the commander system)

Additional discussion is needed to fully scope out requirements
