[CLOSED PR] Clone defects occur based on time since clone scan data saved

[mralexs]

Seems like a good idea to me, making it so prescanning isn't just an instant "I win" button in the event you're murdered. Big problem right now is antags killing someone, and that person getting popped out of the cloner within 30 seconds of them dying. Now it should make it so finding the body is a priority, so you can do a fresh scan and pop them out with no defects, but in the event the body is unrecoverable they're still not shit outta luck. It also encourages people to pop back into medbay to refresh their clone scan.

I have to ask, how often does this happen? On classic I've had to wait over 10 minutes to notice the disk blinking in the cloner unless there is extreme action happening and even then, its not a problem for the antag unless the cloned person gets their stuff back. This is such a major change to cloning and for what? I haven't even seen the benefits for cloning being disk based, only that its more annoying to go through when you have a body right there and you're trying to bring them back.
