Missed last debug line
Caches side effect types to a global list, less loops on addition.
Makes them process only every 15 ticks, to cut down on the calls.
Removes damage because it was supposed to be gone, no idea why I didn't delete the lines.
Replaces long check with lots of get_organ calls with shorter one.
Also changed weird condition that amputated leg must not be splinted.
Removed checks for haslimbs, since movement while downed is not possible anyway.
Moved some special effects for broken limbs after check for such, so healthy ones wont bother.

Fixed a derp in populating the global list of sideffects.
removed some unneeded icon update calls (haha totally unneeded yeah)
replaced complete regenerate_icons with just body_update in case of dropping limb
Healing wounds should properly update damage overlay if needed.
