[MERGED PR] Cloning rack

[Snoid]

i like this change, i love being able to actually grab disks and run, but holy fuck actually managing the disks is a pain. can we just put empty disks in the rack and whenever someone gets scanned it just auto writes to one of them? or for there to actually be some kind of system that prevents us from just printing a fuckton of disks and scanning everyone and leaving all the disks on the floor just in case we recieve news they die. love the cloning nerfs (even if it isnt much), but its a tad too tedious for my preferences as is

also in some positions, lights can block the bottom disks in a rack. probably some other stuff too.
 
theres a disk in this rack. cant see it. (donut 2)
