Please remove the THREE.js requirement for including altspace.js

[AGoblinKing]

Currently you have to include three.js even if you don't have 3D elements.

<script src="http://sdk.altvr.com/libs/three.js/r71/build/three.min.js"></script>
<script src="http://sdk.altvr.com/libs/altspace.js/latest/altspace.min.js"></script>

Ideally you could just include altspace and make use of the firebase connection for interesting 2D applications in VR.

Good point. We should be able to make Three.js optional for 2D apps. I've added this to our backlog.

That may be tricky given that a number of the utilities use three.js classes, but worth thinking about. Perhaps making it easier to use the individual utilities would be a way to go.
