Create user-modifiable URL blacklist to not activate crowdwise on

• Blacklist prevents API calls being made for those sites
• Allow the user to add in URLs via a large textbox / list with elements that can be removed individually (warning: this is unrestricted user input so we have to sanitize it)
• Also add a right click context menu for people to block the current host (x.y.z) or all subdomains (*.y.z) https://stackoverflow.com/a/71655972

• Google maps changes URLs very often (leaks position)?
