OSMF SVN

DVR: Extending stream info retriever unit tests.

PARB changes: removing MediaPlayer.playMode and related classes. Renaming livePosition to lastRecordedTime.

Fix unit test.

PARB changes: Rename DRMEvent's error to mediaError to be consistent with other trait event classes.

Remove duplicate event metadata.

PARB changes: Remove reason property from switching rules and dynamic streaming trait. Should be exposed via logging statements.

PARB changes: Add LayoutMetadata to MediaContainer constructor for parity with base class. Various ASDoc updates.

Reinstate ugly workaround for our build system's handling of projects that have only one source file.

Remove MediaPlayerWrapper sample, it has been replaced by the MediaContainerUIComponent sample. See ExamplePlayer or DynamicStreamingSample for examples of how to use MediaContainerUIComponent. See HelloWorld for examples of how to use MediaContainer in a barebones app.

PARB changes: Remove MediaPlayerSprite, MediaContainer is now the sanctioned way to place media on the stage. Move ScaleMode to layout package. Add MediaContainerUIComponent sample project to show how to use MediaContainer in Flex applications. This will replace the soon-to-be-defunct MediaPlayerWrapper project. Integrate sample apps with the API changes. Note that HelloWorld has been updated to use MediaContainer rather than MediaPlayerSprite, and is the best resource for seeing how to integrate a MediaContainer into an OSMF app.
