Updates: Domains and avatars


Hi All,

As discussed in todays meetup, we are changing the domains and avatars.


We are increasing the size of a domain and putting the origin (0,0,0) to the center of the domain. Here is the PR outlining the change: https://github.com/highfidelity/hifi/pull/5555


We are removing the ability to have a separate head and body for avatars and consolidating around one model file, that supports both head and body. https://github.com/highfidelity/hifi/pull/5566

Let me know if you have any questions.
