Adjust MediaPlayer's stop implementation to take advantage of the new PlayTrait method. Fixes bug where playable media would auto-loop even if loop was false.

Disable pausing for certain PlayTrait subclasses.

A couple of UI fixes for ExamplePlayer.

Remove IDownloadable references.

Fix bug where NetStream would continue playback upon completion (due to our not handling the new STOPPED state). Injection from trait refactoring.

Fix bug in SerialElement where the durationReached event was dispatched on a child-to-child transition due to the base class thinking that the duration had been reached (since the second child didn't have a duration yet). Injection from trait refactoring.

Fix bug in progressive audio seek-when-playing behavior.

Fix reference to old playing property (now playState).

Work around Fix for FM-251, updated for dynamic streaming.

Temporarily disable RTE caused by missing composite traits.
