Change |applyPlayRange| to focus on Timelines
Change |applyPlayRange| to focus on Timelines

In order to support src=, there are some functions in player that
need to be refactored so that they can work with or without a
manifest.

Since |applyPlayRange| is about adapting the timeline, this changes
it to be given a timeline and apply settings to it.
