Brian Birtles 10fd3a5994 Bug 1032573 part 4 - Add AnimationTimeline::ToTimelineTime helper method; r=dbaron
This patch simply factors out the conversion from a TimeStamp value to
a nullable-double value relative to the start of the timeline. This is so that,
in a subsequent patch, this functionality can be reused by ElementAnimation
when it reports its start time (which is currently recorded as a TimeStamp).
