Simple display of numerical value for Energy, Water, Stomach, Blood, Health, Exposure, Shock and any other values of the character state such as sickness, legs state etc.
While this is in alpha state, a debug display will help us see if there's an underlying cause to many of the bugs we run into. This will only get more complicated as you add in new systems.
We don't need these stats displayed constantly as part of the standard UI, but being able to view them in some way will be useful.
