v1.2.0 Native Components and Firebase Sync

As of today, AltspaceVR SDK developers can use A-Frame components to manipulate a variety of native AltspaceVR resources, including architectural building blocks, particle effects, physically blocking colliders, positional sounds, and more! Additionally, we've ported over our Firebase synchronization functionality from the Three.js SDK. These represent a huge jump in the power available to our developers, and we are very excited to see what you produce. For a complete description of the new features available, you should check out the updated A-Frame documentation, and the Native Components FAQ.
