Display UI immediately if displayTimeThreshold = 0

[nicoaldegheri]

In my application I try to update the message set in the ActivityData but I never see that change because setMessage() is called before the timer show the original ActivityData.
This is because even with diplayTimeThreshold = 0, the call of the selector show() is placed at the end of the current execution stack, after my message update.

This pullRequest is proposal to avoid this by immediately calling show() if displayThimeThresold = 0.

Line Length Violation: Line should be 100 characters or less: currently 118 characters (line_length)

@nicoaldegheri: To clarify, your code will look like this (if I understand correctly):

indicatorView.startAnimating(data) // With message "Before change"
indicatorView.setMessage("After change")

Then the result is supposed to be "After change" instead of "Before change", isn't it?

@ninjaprox it's exactly that!

@nicoaldegheri: Is there a specific reason behind that? In normal use case, the message can be packed in data, then change it after awhile by setMessage(_:).

[nicoaldegheri]

Oh sorry, I misunderstood, this is exactly my use case:

myPresentFunction {
indicatorView.startAnimating(data) // With message "Before change"
}
myUpdateMessageFunction {
indicatorView.setMessage("After change")
}

I have some case where myUpdateMessageFunction() is call very quickly after myPresentFunction(). So quickly that it stacked before your showTimerFired() selector in showTimer.

I hope this is more understandable :-)
