GUI support for ct configs

[Nischhelm]

This will allow to register ConfigGroups to show and be modifiable in the ingame Mod Options tab.

To register for gui, add
.withGui() or
.withGui(ConfigUtils.createMeta(modName).setXX...)
to the outermost ConfigGroup before registering.

like this:

import mods.zenutils.config.ConfigUtils;

ConfigUtils.named("test")
    .withGui(
        ConfigUtils.createMeta("Test")
            .setDescription("§4Test1234")
            .setVersion("1.0.0")
            .addAuthor("Nischhelm")
    )
    .rangedInteger("testInt", 1, 0, 10).sliding().add()
    .register();

available metadata to be shown in mod option gui are

• modid (same as file name)
• name (needed, set in createMeta)
• setDescription (auto filled if not provided)
• setCredits (auto filled if not provided)
• setVersion
• addAuthor
• setLogoLocation

Modifications to the stored values will be directly transferred to the registered Configuration object, meaning that scripts in game will automatically grab the modified values.
