js: add support for keydown events (#678)
* js: add support for keydown events This will modify the player behavior even if the player element is unfocused. Based on the YouTube key bindings, allow to - toggle playback with space and 'k' key - increase and decrease player volume with up / down arrow key - mute and unmute player with 'm' key - jump forwards and backwards by 5 seconds with right / left arrow key - jump forwards and backwards by 10 seconds with 'l' / 'j' key - set video progress with number keys 0–9 - toggle captions with 'c' key - toggle fullscreen mode with 'f' key - play next video with 'N' key - increase and decrease playback speed with '>' / '<' key * js: remove unused dependency 'videojs.hotkeys.min.js' Support for controlling the player volume by scrolling over it is still retained by copying over the relevant code part from the aforementioned library.pull/704/head
