Forge Backport progress

What's new?

• few UI buttons didn't work correct
• all teleportations now based on command (u shouldn't feel difference)

What's next?

i guess now EnderBook finished - i didn't find any another bugs so it works correct. when I'll have more free time I'll start to add another books - OverworldBook, NetherBook and BookOfTheEnd. But it will have few differences - this books will be stored saved points inside themselves, so you will able even share your saved points by dropping a book to another player. I also want to change it this way on NeoForge version, but I need to make point-transfer from old system to new (to prevent players from losing their saves)

thanks for attention and thanks for playing with it! if you'll find another bug, please, report
