[1.1.2557] Sedation confusion outlasts sedation

[carbon]

Sedation now has three states. The middle state Sedation (woozy) can cause the afflicted pawn to enter a confusion state and wander around aimlessly for hours.

This would be fine except the confusion state often lasts longer than the sedation effects themselves. I've had at least two pawns already that I've witnessed still be stuck in confusion even after Sedation (residual) goes away.

Unless this is intended to model some real world medical phenomenon I'm not familiar with, confusion should generally go away when the thing causing confusion goes away.
