2020.09.12 Windows/Unix Binaries

Sooo many merges and fixes.

Note: No XP support yet!
Very sorry guys. But next point on To-Do list will be full automatic release (this includes building for XP) hope you can wait until now and compile it yourself in the meantime
Edit XP Support is here: youtube-dlc.exe. However note that this is an experimental binary until more feedback is received! For your regular EXE look at the bottom.
