Shortcut method for cataloged classes

[XakepSDK]

Maybe introduce something like class.builder() for registry requests? e.g. ItemType.of(String) or ItemTypes.of(String)

static Optional<ItemType> of(String id) {
    return Sponge.getRegistry().getType(ItemType.clsas, id);
}

I really like the idea. This would make the class more enum like. Maybe also add a getAll() method .

My vote is for ItemType as opposed to ItemTypes because ItemTypes is meant as a static registry of the vanilla types while ItemType knows about the dynamic registry by ID. Also, I think that .of implies construction and the method should instead be named getById or similar.
