Fix bug FM-194: Calling seek consecutively doesn't respect the last seek. The fix is to let each subsequent seek through (previously we blocked a seek attempt if another seek attempt was underway). Update base unit tests. Modify ExamplePlayer's scrub bar to seek while you scrub, this is a good way to demo/test this behavior.
