Subject: command: add a property to signal whether networking is used

Requested. The property semantics are a bit muddy due to lack of effort.
Anticipated use is different display of cache status, so it should not
matter anyway.

 ``paused-for-cache``
     Returns ``yes`` when playback is paused because of waiting for the cache.
