Better fix for serial seek trait event order bug. Also fixed bug in MediaPlayer where currentTimeChange event could be dispatched on trait addition, even if currentTimeUpdateInterval was zero. Added unit tests for SerialElement holding DurationElements, since that case exposed quite a few edge case bugs.

Fix compiler warning by adding a blank CSS file.

Fix various issues related to serial seek event order, and loading of children when transitioning from one child to the next. Exposed while testing a SerialElement with DurationElement children. Updated unit tests.

Fix bug where autoRewind false wasn't being respected.

Minor cleanup. Add timed image example.

Fix for FM-396.

Fix for FM-348:

Once a video or audio element is loaded, its default time trait is overridden by the permanent versions. However, not all elements have their correct duration set until they are played back. Video elements get their durations from a metadata event that's triggered after play back, for example. To remedy the element's duration going to NaN in between the default trait being removed and the permanent trait being properly set, the NetStreamTimeTrait is extended to take a defaultDuration member. Video and audio elements now forward their default duration value to the trait.

Reenable MediaPlayer+DurationElement tests. Separate testing of MediaPlayerStateChangeEvents from other events, since the state change event usually fires later.

Fix another disabled unit test.

Fix some TODOs in the unit tests.
