Ressources rebranding for Overte
(mostly images, icon, model updated with Overte brand)
some file has been edited to replace some files (they had vircadia in the name)
Most of this has not been tested. (cause I don't build)
We probably don't want to continue with High Fidelity's "voxel" icon for the interface. This changes them to the Kasen logo.
Tested on:
Windows 10 Pro 1909 build 18363.476
CMake 3.16.0
Microsoft Visual Studio Community 2019 Version 16.4.0
