Cybernetic limbs! (DO NOT MERGE YET, CODE REVIEW)

Surgery/helpers.dm 's "Arms" and "legs" Will be removed soon, they are from a first attempt at doing this, I no longer need them and will remove them as soon as I can

Check this Forum thread for discussions: http://www.ss13.eu/phpbb/viewtopic.php?f=10&t=1774

MAIN ISSUES:
No sprites - besides my crap
Minor Visual Bugs - damage overlays remain after surgery will correct soon, Surgery refers to the limbs as "r_arm" In game, will fix as soon as.
Redundant files leftover from earlier attempt, not a bug but still an issue.
I guess this is an issue - you can't remove the new limbs (cloning should fix this if people REALLY want their human arms back)

MAIN FEATURES:
Custom Examine text for having augmented limbs - this is done by a variable, I will use that variable later to make the limbs do something rather than being purely cosmetic (as of right now)
2 surgeries, Leg and Arm Augmentations

We've wanted these for a while, I believe Pete was going to take a shot at it but I guess that never saw the light of day (Pete was probably too busy with !life!)
