Simple Shulker Preview

This is a fairly sizeable update, enough to increment a version!

New Features

• The config is now a lot cleaner, with dropdown sections for position options
• There is now a bar indicating the capacity of shulker boxes. This is enabled by default, so the default item displays have also been moved.
• Added support for displaying icons on bundles
• Added a minimum stack size filter, calculated as stack size * stack count

Changes Thanks to @Wyne10 on GitHub, we have now updated to 1.20!

Note that, due to the significant changes made to the internal MC code, I will likely no longer be porting new changes to older MC versions anymore.
