New Atavism Hub to manage your projects

To make Atavism friendly for both engines, we developed Atavism Hub which will be released later in 2021. The goal of it is to simplify Atavism Editor installations and a project creation process. Because Atavism for Unreal will have separate documentation and tutorials it will also have proper links for both Unity and Unreal in one place, depending on which you will want to use. It's a simple tool but it should be handy to have it.
