Issue Description

What

I need to remove the full screen button, but the only way for doing this is creating a custom controlView subclassing BMPlayerControlView. If the controlView attribute of BMPlayer wasn't private, someone can access the fullscreenButton and remove it from his superview, or set the controlView directly. I added the player via IB so I wouldn't have to reinitialize it or setting constraints using SnapKit
