Fix for bug FM-108 Local progressive URL not working with MediaPlayer. Modified the URL class to handle relative paths correctly.

Minor API change: Use Vector not Array for MediaElement.get traitTypes. Approved by dev team. Should be no impact to sample apps, unit tests, or test apps.

Fix brace.

Removing old prototype code.

Increasing timer interval in attempt to fix unit test on the build server.

Dual threshold buffering example: Reduce buffer time after a seek.

Refactor MediaInfo/MediaFactory relationship to make factory aspects distinct from media definitions. Remove MediaElement.initialize and all of its implementations, dynamic instantiation is now handled by a client creation function. Update all dependent code (sample apps, plugins, unit tests, etc.).

Fixing testParallelViewableTrait from being skipped.

Fix comment.

Add example for dual-threshold buffering.
