* Stethoscope fixes and additions
Now with less ❄️. At least, the species ❄️ kind.
- Stethoscopes now check for a heart and lungs. If the target doesn't
have either, the user won't hear anything. Sure, this means the user
will still hear a pulse if the target just has lungs and vice versa, but
you'll probably be dead or have microbattery or something if you don't
have both.
- Using the stethoscope on yourself will display a message that uses
'your' instead of 'his' or 'her'.
- Using a stethoscope on someone will tell the user if the target is
having a heart attack ("hear an irregular pulse and respiration")
- The messages displayed will properly use 'the'. ("[user] places the
stethoscope" instead of "[user] places stethoscope")
I don't know why I'm bothering with this, no one uses stethoscopes for a
good reason.
* (Hopefully) fixes the same message for lungs but no heart. Also reduces the oxyloss threshold thing. I probably did this very wrong.
* Tully got salty because I stole his PR, so we collaborated
* Rewrites the code to be less shit, probably
