* Updating VREffect and VRControls to support WebVR 1.1

* Stripped out really old WebVR code path that's no longer used.

I'd be shocked if anyone was still attempting to use the browser builds
that the old code path was supporting.

* Ensured that VREffect uses the right eye transforms

Since some view matrices may include orientations as well as
translations we need to extract the head-to-eye transforms from the view
matrices to ensure accurate results. This isn't normally necessary but
is required in THREE.js because the camera is already transformed into
the head position with the VRController.

* Added check to GPUComputationRenderer to make it work on iOS.

It checks if FloatType is supported by trying to render in a temporary render target.
If the check fails, it switches to HalfFloatType which works on iOS.

* Changed the detection method per mrdoob indication.
