fix(lightbox): Implemented listeners for resize and orientationchange events

Also removed global CustomEvent polyfill. Patched eqjs, now uses a factory CustomEvent. MDL is has
it's own CustomEvent polyfill which fails when a global CustomEvent polyfill is applied. Hopefully
the MDL team will fix this.
