attackthrottle {rate} {time}
rate: chance to cancel attack (must be between 0.0 and 1.0)
time: in seconds, how long should this entity stay tame until next check, the engine will generate a random number between 0 and this value.
note: some action will cancel the timer, for example, getting hit. Seeing the target block or attacking will also affects the timer. A value of 0.5-0.75 should be OK.
the idea is to allow using high aggressive settings to give the AI super quick initial "reflexes" but still enough delay between subsequent attacks to avoid unbeatable cheapness
