* Finally use exponential decay algorithm for greenzone
* Works in both directions (unlike fceux taseditor)
* Stop using last accesses states for anything
* When dropping states per project save, account for state gap better
* Use _states.Keys[i] instead of _states.ElementAt{i).Key in speedy parts, because it's apparently tons faster
* Use StateIsMarker() where it's supposed to be used
* Markers are still left untouched
* Branch states are still dead (probably forever)
