[rules-users] Evaluate rules for multiple facts of the same type within a StateuflSession

[Wolfgang Laun]

It's clear from the log that the first activation ("ONE") is cancelled
by some action in rule TEST, since the cancellation is bracketed
between Before- and AfterActivationFired of the activation for "TWO".

I dislike the artificial creation of mysteries - as if we hadn't enough without.
