Changing WebUI port

Qbittorrent doesn't handle it well when changing the default webUI port. If you change the port you will likely be greeted with a blank page served with an HTTP 401 response.

In order to get it to work, you need to change the default webUI port with a new variable:
-Remove the port mapping for 8080
-Add a new one with your new port preferred port
-p 8085:8085
-Add a new variable called WEBUI_PORT and assign the new port to it
-e "WEBUI_PORT"=8085
