Describe the bug

It's not possible to insert non-book items into bookcases by hand. However, automated item movers from other mods, such as AE2 storage buses and export buses, ignore the restriction.

I'm not a Minecraft modding expert, but I think this is because BCBlockEntity's item storage is done by implementing Container, which the Neoforge docs seem rather insistent is only retained for vanilla compatibility.

If that is the cause, then rewriting the storage logic to use IItemHandler seems to be the thing to do.

Steps to Reproduce

Create a basic AE2 network with a creative energy cell, chest connected to an import bus, and a bookcase connected to a storage bus. Put a fish in the chest. Wait a moment for the fish to be imported and stored in the bookcase.

Expected behavior

Automated item movers should respect the "books only" filter on bookcase slots.
