Grandmother of 50 872817b70b Mood Code Improvements [Merge-Ready?] (#39075) 
fix: having higher sanity is no longer punished by making you enter crit faster
balance: you can have 100 mood instead of 99 before it starts slowly decreasing


Remember higher sanity is BETTER

You want crit_modifier (now crit_threshold) to be LOW so you can stay in fights more (you go into crit at 5hp vs 0hp).

Why: Proc overhead, puts the load on mood, proper abstraction of mood component, values > defines, etc.
