Survival Overhaul [ABANDONED]

Additions:

*  Heart fruits now will occasionally generate in certain underground loot chests. Eat them to restore your health and gain an additional heart of semi-permanent health!

*  These hearts will go away on death (configurable), so... try not to die.

*  Currently they're non-renewable, but I do want to add an associated plant at some point.

BUGFIXES:

* Thermometers should work properly at extremely high temperatures.
