remove flashbang rushing

[Dickles]

I don't think flashbangs should be able to stun, but I wouldn't mind if their disorientation is buffed as a trade-off. More messed up movement and a chance to drop items would be good I think. Maybe some stamina damage but it's capped?

Flashbang rushing is only good because it stuns someone without having to click them and there's nothing they can do to avoid it. If the stun was gone I think it would be fine.
