More strict when it domes to audio/video desynchronization.
Brand new UI for the video player:
Much more iOS 7 friendly.
Do not display meaningless zeros in the time left or played.
Remove the volume slider.
Remove the pan gesture (a bit too much experimental in my opinion).
Still remain a little glitch in the UIToolbar element positions, when switching between pause and play states.
Fix a few iOS 7 deprecation warnings.
When playing music, during the vc appearing transition, the background of the player is not transparent anymore.
