Add functionality for removing domains

[ChrisChrome]

The websocket for sinking yachts has a remove request that isn't used yet In hindsight we shouove implemented it when we were doing websockets. There is always the possibility that a false URL will make it into the system

This will take like 3 lines to do, just implement it?

This was moreso a note-to-self But was public in case anyone wanted to do it real quick, I was at work when I wrote it
