adds polyfill sourcemap

[caseyyee]

Fix #54
also moves this into the main templates folder.

just to be consistent with all the other library usage.

probably time to add a js folder

As a note, Polyfill ver:
https://github.com/immersive-web/webvr-polyfill/releases/tag/v0.9.36

ok took materials.meta and models.meta

@caseyyee I see this in Safari on iOS:

I think that's out of reach. The Unity player exhausts device memory. This is also happening in Chrome and Firefox from time to time.

[delapuente]

Well, not out of reach but it requires optimizing the Unity loader and probably do more than JS to fix it.

[cvan]

you can manually bump the memory size from the Unity WebGL Player Settings or the emscripten module loader options in index.html

This is duplicating #54 according to the current wording. I'm going to close that and test and merge this.

For the posterity:

1. We'll add an out-of-memory-related entry in the FAQ
2. We are tracking how to update the polyfill in upgrade version of webvr-polyfill dependency #113

If you see the error regarding requestAnimationFrame and described here, open another issue.
