Instead of enabling it only when a stream-cache is enabled, also try to enable it independently from that if the demuxer is marked as is_network. Also add some code to the EDL code, so EDLs containing network streams are automatically cached this way. Extend the OSD info line so that it shows the demuxer cache in this case (more or less). I didn't find where or whether options.rst describes how the demuxer cache is enabled, so no changes there.
