[rules-users] fireAllRules performance

[Mauricio Salatino]

fireAllRules will only fire all the rules that where activated during the
insertion phase. So basically when you call it at the end, it will only fire
all those rules activated. If you insert a fact that doesn't activate any
rule you don't need to call fire all rules.
