Adding a LayoutUtils.setLayoutRenderer helper function.

Fix bug FM-119, where the playhead time doesn't get updated until after the seek has completed. The bug is actually in Flash Player (FP-1705), and the workaround is to wait until NetStream.time gets updated before dispatching the seek completion event. This changelist also updates the unit tests and NetMocker to verify the fix.

Refactor MediaPlayer unit tests to make them injectable by MediaElement. Add additional unit tests for injecting various MediaElements into a MediaPlayer.

Add DRM DLL update support

1. IDataTransferable support
2. Anonymous playback support

Fix for FM-106. Fixed small ASDoc error in Seekable Trait.

Reverting to MediaPlayerSprite, from Region Sprite.

Fixed critical MediaPlayerWrapper bug.

Reverting changes made on rev. 10644, for they seemed to be the cause of ExamplePlayer having scaling problems, and not removing prior samples from its view.
