[MERGED PR] feature: apply sonic stun from flashbang to deaf mobs

[coolvape]

if deaf just becomes an "RP" trait with no combat benefit, how is that still not a net-negative for those around them? There's lots of traits that make communication incomprehensible(half of the accent traits do this).
(i still like this change, just thought it was an interesting point to argue - the current state is not ideal)
