Add configuration screen

[TheGridExpert]

Added configuration screen for Farmer's Delight using NeoForge's new features.

Important side changes:

1. Removed configs for wild crop generation as they weren't used anywhere and affected nothing. Hope I didn't miss anything.
2. Removed comments above categories (e.g. above "world" category there was "World generation"). This was done because NeoForge turned them into tooltips under category tooltips on the screen. For example under the same "World generation" there would be another "World generation" but one line below. I've tested this in my own addon mod, and there seems to be no way to fix it other than to remove the comments.
3. Removed the "Client settings" category because... it's already client, and in the menu it looks like you have "Client settings" inside of "Client settings". All three client configs are now located straight in the client config with no additional category.
4. Added extra pain for translators, as all config now have two translation keys per config. Well, at least we now have translatable configurations /:
