First version for NeoForge 1.21.1. Requires ModderNameLib.

• New item: Sticky Syrup. Apply it to a package to make it sticky. Sticky packages remember their item even when they are empty.
  • This replaces the old system of packages becoming sticky when they are next to a slime/honey block. Not many people knew about it!
  • The old system is available behind a config option.
• Tweak interactions with regard to sticky packages. (For example, you can insert items into an empty, sticky package, even if they aren't items from your hand.)
• Remove the annoying honey particles from sticky packages. Sticky packages can now be distinguied by "sticky" text that appears when shifting.
  • It is behind a client config option, if you want them back for some reason...
• Stickiness might actually work on Forge!!!!! (lmao) it wasn't being enforced through the IItemHandler.
• Slightly less willing to be placed vertically. You have to look up/down a bit farther.
• Fix an issue where items which stacked to 16 could be deleted using Packages inventory interactions.
• On 1.21.1, PackageBlockEntity no longer implements vanilla Container! Instead, modloader-specific inventory mechanisms are used.
  • On NeoForge, the Package exposes an ItemHandler capability. On Fabric, the Package exposes an ItemStorage API.
  • This was a rather large change so I'd like to test it before backporting it to 1.20.1.
• On 1.21.1, the Package item also exposes these modloader-specific inventories.
  • This means other mods which can, e.g., pull blocks out of shulker boxes in your inventory, may be able to pull items out of Packages too.
  • This feature needs more testing.

On NeoForge, enable the "NeoForge Light Pipeline" in Mods -> NeoForge -> Client settings -> NeoForge Light Pipeline. This will improve the apperance of the Package Crafter.
