Player HUD

Player HUD Update

-Updates a few of the existing HUD icons to be a bit more clear:
--Oxygen deprivation, Toxins, Pressure, and Hunger

Health Icon split into two separate icons:
-The traditional body-health icon which shows your total health is now a heartbeat monitor instead (still tracks your total overall health).
-Second one is the familiar body-health icon, but this one changes color on specific limbs to show how much brute or burn damage a particular body part has taken (this does not measure toxin, clone, or oxyloss damage). Should make it way easier, for example, for IPCs to determine which limb is damaged and which is ok (traditional self-examination will still work).

This required more work than I had originally hoped; had to break the sprites down because we have more than double the external organs--likewise, had to go back and retweak a few times to make sure all body parts were fairly clearly highlighted when they did actually take damage.
