In forthcoming patches we will encapsulate AnimationPlayer::mStartTime so we can ensure that related state is updated appropriately. We would like to expose mStartTime via GetStartTime() but currently a method of that name returns the start time as a double. This patch applies the pattern used for currentTime to startTime; specifically, GetCurrentTime() returns the TimeDuration (since that's what C++ callers should use) while GetCurrentTimeAsDouble() returns a double. At the same time, this patch also removes the [Pure] extended attribute from startTime in the WebIDL definition since subsequent patches either in this bug or in bug 927349 will mean that startTime can be updated out-of-band. Specifically, we will implement deferred playback of animation such that the startTime remains null until we've finished rendering the first frame of the animation.
