Detect inserted optical media fixed

This has been a bug "under the radar" for a long time. I never noticed it, because I never use optical media. Forum member CF-DKS reported inserting a CD and the icon did not appear on the desktop:

https://forum.puppylinux.com/viewtopic.php?p=155986#p155986

The pertinent script is /usr/local/pup_event/frontend_change, which is called by the /usr/local/pup_event/pup_event_frontend_d daemon when any disk change is detected. The script queries the optical drive by running a little binary executable named 'cddetect_quick' ...but it isn't there.

It is supposed to be there, but I found that I had typed the package name wrong. It is a package compiled in OpenEmbedded, for Scarthgap, and the name is 'cddetect-quick', a dash, not an underscore.

Fixed, so now, when an optical media is inserted, it should appear on the desktop, along the bottom above the tray, and it can be clicked on to run an appropriate handler.
