[Feature Request] Import/Export of .nbt files

[KadTheHunter]

It would be amazing if IBE had the ability to save items to .nbt files, and import .nbt files via drag-n-drop to the Inventory screen.

An example of this is NBT Editor v1.10.0 which can save items to .nbt files via /nbt export file, and load .nbt files when you drag and drop the file onto your inventory screen.

Personally I prefer IBE Editor over NBT Editor (better UI, easier to use, more features, etc.), so it would be much appreciated if this feature was added :)
