Windows client 3.1.0-alpha1

Important!

This is a complete rewrite of the Bluecherry remote client. Literally none of the code base from Version to Version 3 was reused. This means some things may not function as expected and currently PTZ does NOT work. If you have a PTZ camera and would like to help test please let us know in the discussions area - https://github.com/bluecherrydvr/unity/discussions

What's Changed
