Show current dBm in the Librarian menu bar

It occurs to me that unless one is looking at the settings menu as the superuser there is no way of reliably knowing that you are indeed receiving a signal. Sure, there is a signal strength graphic in the top right of the screen but that doesn’t really tell you anything.

Can we add the current dBm reading next to or under the signal graphic?

When there is a reliable lock and file download, a down arrow appears next to the signal meter. But yes, there should be a more immediate way to tell if all is well. Will make this better on Skylark.
