Floppy disks can no longer be "formatted" by shift-rightclicking, added crafting as alternative.

Simply recrafting a single floppy (no other items in the crafting grid) will now format it. Same for loot disk, they can be converted to normal floppies the same way.
In general, this removes the "shift-right-click to remove NBT tag" functionality, so you also can't format HHDs like this anymore - use `rm /*` or such.
If you notice any items that needed the old functionality (looked through the list, didn't see one), let me know.
