P0-A8: Part 838: 2020.2 Port

The port is now basically done, but I do need to do some more testing.

I have a minor ongoing issue with the voice recognition keyword recognizer. I am getting an error, but the system works, so this is not a priority.

I had some more serious errors with the shaders for my weather asset, and the Oculus avatar, but I was thankfully able to replace the shaders with others that worked just as well.

I am also using the port as an opportunity to run additonal tests on all aspects of the project. I have already found, and fixed, some minor issues with other systems that I hadn’t tested in some time.

I have also made some improvements to the text-to-speech system in my project. I have added the ability for each of my AI characters to have their own, unique, voice.
