Make damage knock you out of stamina-stuns

[TDHooligan]

which it would inject 

chem life ticks are every 2~4 seconds (the time it takes to get more than 1 hit in, maybe more if lag is bad) and chem is also not really designed for this use case. 

if this were to be strong enough to actually fix what this change targets, it'd have to give you an insane quantity of stamina. whereby you could exploit all the other systems in the game (kidneys, slow metabolism) to get more than the desired amount of stamina

it would also be purged by any purgatives (which are not related to this change at all)

you'd end up with a laggy, unintuitive, buff of variable length that could be useless for 1 person and overpowered for the powergamers.

all to beat a simple, hard and fast rule of 'someone hitting you will knock you out of stamina stun'
