For channels it could be useful if channels that are no longer backed by any services could be (semi) automatically removed.

Obviously we still want the ability to have empty channels, as this is needed for several intermediate steps when setting things up. But it could certainly be useful to have a button that removes unused ones in the event a user has removed a whole bunch of services etc...

I have some test code for this, but it still needs cleaning. I do want to include this though.

The current logic is a bit different - services are disabled when they're not present in service info tables now. Users may remove them manually through WEBUI - delete button. Also, we track times for muxes and services (last seen), so the dead muxes and services may be removed using these criteria, too.
