Goal of this was to do initial ES6-ification of these modules with import/export, not a full ES6-ification of everything. Wanting to use sensor polyfill for adding the Generic Sensors API (via #10), which would need a ES6 module loader anyway, so this is a good time as any.
Also removed the vestigial TouchPanner (outside of polyfill's jurisdiction), as well as a vestigial Util.race (used in webvr-polyfill, not here).
