Timeline play() and seek() when completed

[tomsercu]

I believe there's a bug with the behavior of play() when a timeline animation is completed (fwiw I also have autoplay: false).
The animation restarts, but TL.completed (in chrome console) shows false.
When triggering play() again in this fake-restarted state, the animation is interrupted and restarted.

And kind of related, when using TL.seek(t) with t<TL.duration, the TL.completed flag stays false, and TL.play() has no effect. This behavior seems wrong also.

I have the following fixes for now:

mySvg.on({
    // Some kind of playItSafe() function which doesn't fake-restart.
    mouseenter: function() { TL.completed ? null : TL.play() },
    mouseleave: TL.pause,
    click:      TL.restart
});
seekbar.addEventListener('input', function() {
    if (TL.completed && seekbar.value < 100) { TL.restart(); TL.pause();}
    TL.seek(TL.duration * seekbar.value / 100);
});

Confirmed that this works for me on the canary-59-debug branch. Thanks for the fix!
