- crouching (allows placing signal items at the bottom of a room and may be useful when doctors are added (CPR animation, using medical items on dead bodies?))

- changes to the dying logic: characters will be unconscious when their health or oxygen goes below 0.0, and die when it drops to -100.0 (if either of the values is below zero, it will automatically decrease so the character will quickly die without medical care)
- fixed LightSprite being drawn on LightComponents even if the item is inside an inventory
- characters extend their arm more when placing signal items
