Playlist Catalogue: fix: "Save Current Playlist" may fail silently
- After rebooting, unless the current playlist
had been manually resumed already, the "Save
Current Playlist" option in the root menu's/
playlist catalogue's context menu failed to work.
- Eliminate error message attempting to view current
playlist when no control file present.
