Improves legacy item performance and refactors PlayerInteractListener
I think the CachedSet was used wrong. I tried refactoring the class and properly check and add ItemStacks to it properly. If the user reports back with performance issues still persisting... Honestly I'll just remove support for legacy items in general. Server/Users had enought time to redeem them by now. CachedSet is using a WeakHashMap which might actually make the whole Set useless but I didn't do any testing on that today
