Add an option to apply never proxied domains to browser extensions

[cohesive-flight]

When a browser extension attempts to connect to a domain that's been set to never proxy, its DNS query will still do so. This is apparent when using a domain defined only on a local DNS server, as it would be inaccessible elsewhere.

Example:
I have a local password manager service running with the domain 'pm.home.arpa'. Since special-use domains are not yet exuded from the proxy, I've had to set the domain to never do so in order to access it through the browser. However, if I instead use a browser extension to access the service, it gets a network error, meaning its DNS queries are still being proxied despite setting the domain to never do so.
