Disable webvr-polyfill controls and implement our own

[brandonocasey]

Right now this plugin watches window for touch/keyboard/mouse events. Which means that any interaction on the page will move the camera in the 360 video. This is probably not something that should happen, but the only way to fix it is to roll our own controls and listen to events on the video.js player only.

Steps:

1. Use the window.WebVRConfig from plugin.js to set:

• MOUSE_KEYBOARD_CONTROLS_DISABLED to true
• TOUCH_PANNER_DISABLED to true

2. reimplement mouse/keyboard controls using webvr-polyfill/src/mouse-keyboard-vr-display.js as a base
3. reimplement touch controls using webvr-polyfill/src/touch-panner.js as a base
4. Possibly turn of Cardboard VR, and reimplement only in fullscreen?
