*****  fix me:
- check m3uItemGetList if correct now - blind fix from tlmb
- calling delete current songlist widget will delete the widget but not honor any changes - do we allow changes to current songlist? Then we will have to connect this to the delete slot of the song list widget to check there for any changes.
- make menu icons for player larger
- Speicherzugriffsfehler on exit?
- while setting playlist - when loading playlist without #EXTM3U , warning ist shown, but entry not invalidated set to something else even iM3uLoaded should not be set to 2 in plCurrentLoad or is it called elsewhere? Testing needed
- in setPlayListWdgtShow we currently do not care if the old playlist is no longer valid/could be loaded! Might need to create a temporary one or set current to ""
- m3uItemGetList does not have a robust (any) error handling so far


*****  feature
- when showing song list: change order of songs? allow dropping songs from list?
- edit playlist: add try getting song name from tag if not in m3u
- add current song & show song info: can we get better meta data from container formats: mkv, webm ?


*****  ideas ?
- edit playlist: allow editing song name - but need to update tags then as well !
- switch to songinfo widget to show song info??
