Feature Request: List/add/remove Valet proxies.

[adrianspacely]

I work with an SPA frontend. We valet proxy subdomain.ourapp localhost:8080 so that subdomain.ourapp.test serves the Vue dev server we're running on localhost:8080.

Would be great if PHP Monitor could list and manage valet proxies.

I've reopened #105 and if there's more demand for this I'll take a look!
