More complicated Config Menu options

[Gunsmithy]

The current Config Menu, #2, only displays a few pre-baked options for simple options and does not provide options for the complicated ones at all like URLs, keys and names. Giving the user the ability to create their own list in the config file that they would then choose from could be beneficial, allowing them to swap out between a few pre-loaded options of their own/possibly overriding even the options for the simple lists. This could be achieved by moving the pre-made lists to global variables that are set by the Config Parser.
