OSMF SVN

Created branch sprint10-candidate.

Fix for FM-256: Since progressive subclips are not supported, ignore subclip params for progressive files. Also document this lack of support on StreamingURLResource.

Fix bug FM-469, FM-470 and FM-449.

Clarify expected args for LoadFromDocumentElement, as exposed by FM-269.

Fix for FM-255. phone.flv now detects size, and dispatched events correctly. Render wasn't 100% accurate, onFrame instead is being used.

Fix bug FM-258: Seek doesn't trigger seek complete event until playhead reaches target seek time.

Mark synthesizer API as @private.

Removed empty plugin directory.

Apply default layout metadata to ExamplePlayer. Update layout metadata for specific examples now that we're using the default MediaContainer.

Apply layout to the HelloWorld samples.
