hoo boy

replaces all mentions of bodypart_robotic with is_robotic_limb() where possible, adds BODYPART_HYBRID, adds helpers for organic / robotic limbs (is_robotic_limb() / is_organic_limb(), with a arg to override it accepting hybrid limbs)
Also makes the the surgery to heal robotic limbs work if the torso isn't a robot, but rather if there are robotic bodyparts, makes the IPC brain repair.. only accept IPC brains (obviously), makes the damage threshholds for robo-limbs vars instead of a fix 25 with hybrid ones predefined at 25 / 15 (trigger / mindamage), adds an error message to fixing them if already at theshhold, etc. Now just for replacing BODYPART_ORGANIC with is_organic_limb aswell where applicable.. also actual values for the other robo limbs. Fun!
