Some Texture changes and an Item Removal

The changelog on this end will be short and sweet, but head on over to Vanilla++ to learn about all the stuff that this new version helps to add over there!

• Changes for Some Nintendo Items: Previously, I had the Mushrooms from Mario and the Ocarinas from Zelda. After lots of feedback on the YouTube video I made, I've decided to revamp these, but not remove them entirely. The mushrooms are now more Vanilla Minecraft-inspired, being called "Mutated" forms of 4 fungi from the game. They still function the exact same. As for the Ocarinas, those are now called Flutes and have been retextured accordingly. The Music Disc "stal" uses flutes in its instrumentation, so I thought it would be fine to keep them. I AM debating removing them, but let me know what you think about that and if a lot of you actually use these items during normal play or not. I have elected not to remove the Nintendo hats, as those are almost entirely meant to be used in multiplayer, and since they don't add unique functions/abilities I see no need to get rid of them.
• Heart Container Removed: after taking some things into consideration, I've decided to permanently remove the Heart Container item from the pack. I'm sorry to anyone who liked it, but I wasn't satisfied with its implementation, and I couldn't figure out how to have a good cap on its abilities. However, if you want a way to kinda-sorta permanently upgrade your max health and you don't use this pack on Realms, head on over to Vanilla++, where I've added a new enchantment for Chestplates and Elytras that upgrades your max health!
