Make "Shutdown" a playlist option

[Materdaddy]

Per user request, an option for shutdown should be added to the playlist generation. Similar to the check-boxes for "first once" and "last once" items, a "shutdown after playlist" should be added to the schedule options or something similar.

This can now be done with script and event scheduling.
