OSMF SVN

Add unit tests for HTML bridging.

Remove preload example, it's confusing and not a best practice. The use of defaultDuration is preferred.

Fix FM-811: Metadata events not dispatched through SerialElement. Removed obsolete code related to child metadata events. Updated unit tests for both MediaElement (through which the events are dispatched) and CompositeMetadata.

FM-816. Removed Import of mx.utils. class, which isn't referenced in code. Brian to review.

Added more verbose DRM logging to the OSMFPlayers debugger module. FM-657. Brian to code review.

Fix for FM-770.

Update UnseekableProxyElement example from ExamplePlayer to re-enable seeking after playback completes, so that rewind works. No framework changes. Addresses bugs FM-802 and FM-803 (as filed in Galaxy).

Modify HTMLElement unit test to extend base MediaElement test.
