Fix FM-824: Cannot know currentChild of SerialElement generated by a plugin. Update unit tests to verify.

Fix bug FM-826. Here is a summary: when the data in a fragment is mangled, http streaming starts to encounter bad box type and bad box size, such as 30 billion bytes. For any "unfamiliar" box type, http streaming will skip the box based on the box size. However, there is a flaw in HTTPNetStream that cast the bytes needed to int type. This will generate a negative value for bytes needed, thereby breaking the logic. The fix is simple, change from int type to Number type. The if clause is just a safe guard.

Another attempt at fixing the unit tests.

Attempted fix for unit tests failure.

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.
