Radios are found while another radio is running. A B200 - or any SoapySDR radio - now appears on the patch page's Radio list beside an RTL-SDR the receiver is using. Before, the search for SoapySDR radios did not run at all while a radio was open, so a B200 only appeared once it had been put into the receiver itself.
Only the open kind is left out. The search asks every radio driver except the ones whose radio is already open, because their probe would reset it. A running RTL-SDR, B200 or patch radio is never disturbed by it; tested on an RTL-SDR and a B200 streaming together with the search running beside them.
On the patch page: it looks for radios when it opens, each Radio part has a Look for radios key, and the receiver's own radio is listed, marked as lent to the patch when it starts. A patch radio now waits for a search in progress before it opens.
