NBT Editor

IMPORTANT: /hideflags, /max, /unbindskull, and /lore have all been moved to /itemfactory.

/removeflags (an alias for /hideflags) as been removed completely.

Main Features:

 - The item factory system, which includes (other than the four commands above):

    - An attribute editor

    - A block state editor (for BlockStateTag)

    - An enchantment editor (Ctrl+Click is still supported and recommended)

 - There are now scroll bars

 - You can configure the scroll speed of the mouse wheel for NBT Editor related menus (/nbteditor config)

Small Features:

 - The previous screen is shown underneath the confirm and text/number input dialogs

 - The text/number input dialog will now visibly disable the confirm button if the input is invalid

 - The /hideflags screen now uses the new item editor system to match with the other item factories

Bug Fixes:

 - Using Ctrl+Click on armor slots now works properly

 - The save button in the nbt editor will no longer flash right when you open the menu

 - The /open message has been updated to include the 27 slot requirement

 - Ctrl+Click now works with extra high level enchantments

 - When using /nbt on an item with an empty key, a confirm message to fix is shown. The message has been updated to specify that the empty key will be deleted.

 - When canceling the empty key warning, you now go back to the previous location (like the client chest), rather than closing everything
