VideoPlayerViewController: New player foundation

This adds the new player foundation and the work of @diogo.simao-marques, which shall be iterated on.

By default, this interface is enabled in the settings.

Things that needs to be worked on which a ticket will be created for each:

• Interface issues in the more options (...) action sheet(nav title, animations).
• Chromecast interface linking and testing.
• External screen testing.
• Pan gestures handling(brightness, volume).
• Swipe gestures.
• Upon rotation play pause icon is reset to default state.
• Missing double tap gesture indicators.
• Rotation lock icon and feature.
• Plug equalizer from branch.
• ...

changed milestone to %3.3.0

added Interface label

Looks good to me overall. Nit-picks:

• Remove comments such as // TODO: Stopped here refactor
• Remove "New" prefixes for class names. Unless there is a name space collide, it is the actual name and not new. (because, for how long will it be new?)
