refactoring JS -> HTML

Browse Source 
second part of refactoring: JS -> Python HTML
Updated JS code to reflect the change that some HTML generation was moved to python side.
Fixed fullscreen bug - now controls are shown properly below the video. Made the transparency a bit more faded for captions in normal mode.
Fixed bug with captions. Now the attribute show_captions correctly removes them when set to true.
Work in progress.
