-- Terminology: "Thirst" vs. "hydration" --
-------------------------------------------

"Thirst" is the absence of "hydration" (a term suggested by
everamzah on the Minetest forums, thanks!). The overall mechanic
is still called "thirst", but the visible bar is that of
"hydration", filled with "hydro points".
