Performance Optimizations

Don't use A-Frame PolyfillControls helper

The PolyfillControls helper has some breakage where it doesn't
always use the polyfilled VRFrameData class. Also, we don't even
want the pose data to be applied to an Object3D, so it seems a
little bit silly to use.

Performance tweaks

Bump A-Frame to recent master

This was renamed in three.js r93.

Check if browser is an iOS uiWebView

Bot logging

point to latest networked-aframe dev fork

If it is, don't allow user to enter in 2D. Instead, prompt the user to copy the URL and open it in Safari.
