Traveling Tunes

Music Discs are redistributed through the world. 

• 11, 5, and pigstep have been unmoved, the rest can be found through new drops or in other structures, best of luck

Disks can be copied on a grindstone.

• Putting 2 disks on a grindstone will make a copy of the top disc.
• Discs have "Editions" to show how many generation since an original disc
• Disks have "Copies" to show how many times its been copied
• Disks cannot be copied if editions + copied is more than gamerule `discCloneLimit`. 
• if `discCloneLimit` is -1, discs cannot be cloned
