[1.16] Disabling Modules Removes Things in an Unclean Way

When a module is disabled, the items and blocks are simply not registered. This causes issues, especially with the guidebook. When items are removed, categories lose their icons, and disabled modules are still displayed inside, however, some have their description text removed. I have two solutions:

1. Only remove crafting recipes and potentially functionality of disabled blocks/items.
2. Don't register items and blocks (which is current behavior) and: remove guide pages containing unregistered items/blocks, do not display categories if there are no registered blocks/items documented within, and either use a placeholder icon or dynamically select a different block as an icon for categories that have their icon block unregistered.
