Units accumulate damage in the local variables
"ACE_Medical_Engine_$HitXXXX", but these are never reset. The way these
vars are used is as a single-damage-event tracker, and the end result of
not resetting their value when they're done being used is that a
specific $HitXXXX can accumulate enough damage to cause the "select
wound with highest damage" code to always select _it_ for the next wound
event, even if it wasn't the primary target of the last wound event.
I.E. I get shot in the right leg badly. If I then get winged in the left
arm, that wound will end up on my right leg, because when the code runs,
it finds QGVAR($HitRightLeg) > QGVAR($HitLeftArm), and so it applies the
wound to the right leg.
Improves the way medical is storing variables in object space by having
a common list of variables names as macros. Makes the code a bit cleaner
and ensured consistency across components. Also a handy reference for
when working on medical to see what values are all stored.
