Registering Backpacks

Register backpack items from Java with optional row counts.

Java registration

Use this when your mod owns the backpack item.

BackpackGearApi.registerBackpackItem(MyItems.COPPER_BACKPACK, 4);
BackpackGearApi.registerBackpackItem(MyItems.DIAMOND_BACKPACK, 6);

Rows

Rows are metadata for tooltips and integrated backpack UIs. Your mod still controls storage implementation.
