Add TraceNetLoader to ExamplePlayer, to simplify tracing NetStatusEvents for various examples.

Fix bug where progressive audio wouldn't loop. Updated progressive audio unit tests (which are still disabled due to build machine issues, but which do actually run and should be run from time to time).

Clean up comment.

Fix bug FM-708: Looping sometimes fails when audio delay is present in progressive videos.

Fixing bug FM-671.

Fixing FM-692. Changing DVRCast information to travel over the media resource rather than a custom net connection. Updating client classes and unit tests.

Fixing FM-677: changing fps meter's postfix to " Flash frames/sec.";

Fix FM-620: Looping with SerialElement containing DurationElements would fail, due to the seekingChange event being dispatched too early. Added unit test to catch this.

Fix bug Fm-604, FM-691 and FM-680.

Fix bug FM-686: When autoPlay and autoRewind are true, SerialElements may loop on completion. Added unit test to verify the correct behavior for all media types.
