Version based on AMD modules (require js)

This release is the latest one, that is based on the original Virtual World Framework AMD modules (require js).

Features:

• All VWF components and worlds are described in JSON format.
• No world states by default anymore. Every saved world is a prototype.
• From these release, there is no "super" user, who own proxy components. Now every user could own it's own proxy and built the world from corresponding components.
• Finally add support for Oculus Quest/VIVE/Windows MR/Gear VR headsets in all spaces by default.
• Teleportation controls, when using HMD headsets.

Version based on YAML protos and World states.
