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

[GARGATHUGANOKSREVENG]

PR "Why's this needed?" Updated:

Getting a pre-scan early into the shift is a zero-risk way to largely eliminate the danger of death for the rest of the round. This change encourages getting clone-scans only before knowingly risky activity, without removing the ability to get a pre-scan entirely.

That's not how it works, for a lot of risky activity ingame. The pacing of SS13 is incredibly slow and most tasks can take up to 20 minutes to complete, especially when it involves RNG. Miners are going to be severely punished for this on ocean maps. Nobody wants to drag a dead rotting body from the bottom of the acid ocean on nadir, when drones or sea critters are all over it. It's game over for the miner, because he'll either never be revived, or have a giant chance of being cloned with the puritan defect and not be able to play the round again. 

Giant counterpoint to the false statement people having a lifeline against antagonists is a big problem for people playing antagonist: You spawn with 0 gear. You're a stupidly easy target for the antagonist now, and most of them thrive off of your death. Why would a vampire or changeling complain about another body to eat.

Oh yeah and with this PR, instead of just being a huge naked gearless target you're a huge naked gearless target who has arms for legs, or less max health, or falls over when out of stamina, ETC. Or you just explode. For the crime of wanting to be able to play the game, installed because one person thought playing the game was boring.
