playoutDelay should use milliseconds.

[jan-ivar]

W3C design principle § 8.3. Use milliseconds for time measurement says... well, exactly that.

Let's not spread the mistake from stats of using seconds (which I feel personally responsible for) to more specs!

Since no browser implements this feature correctly yet — fortunately, Chrome only implements a cousin named playoutDelayHint that fails to throw on input validation — I still see an opportunity to correct this.

A reason to contain this to stats would be fixing it someday with something like getStats({timeunit: "milliseconds"})
