remainingIterations is now decreased before notifing observers

[ybeapps]

Hi, Great Code - Solved my unfiring timer when user drag content (imagine a quiz without a timeout LOL)

Well, in "timeFired()" maybe it's better to update the state of the timer and then notify the observers?
because the observers might use the timer state to update UI, and if I check "remainingIterations" I'll get 1 - but it's 0... and the last iteration that my code excepts will never happen =]
