[bug] Indefinite Crit: Ocular HUD

Ocular HUD lasts an indefinite amount of time with MUL-T's auto nailgun if continuously attacking. I think the item just considers this one long attack and so the 100% crit lasts until the attack stops since it was initially in the 8 sec time period. Have yet to test on whether or not this will work for other characters such as the engineers turrets or anything else that keeps an attack state up.
