Filtering Hoppers

Some more mistakes I need to fix and new stuff... Here goes!

• When running on Paper, the plugin now registers using Paper's system instead!
• With the update above comes new command organization! /fh item-collection is moved to /item-collection!
• This also means that permissions under filteringhoppers.set.item-collection are moved to filteringhoppers.item-collection! (This should be the last time I move permissions, sorry!)
• Fixed compatibility with Folia for items moved from any container to a hopper (the event wouldn't be fired because of a listener priority issue)
• Fixed an issue that would let items through the filter that shouldn't because of an early return when moving from any container to a hopper
• Brand new plugin overview both on Spigot and Modrinth!

This update means better compatibility with Paper and better maintainability for me in the future. I hope your day goes well, and that you enjoy FH as much as I enjoy maintaining it!
