Launch Exaile and Play Audio CD when inserted

[Adam Olsen]

A nice feature would be if Exaile could open and automatically start playing an audio CD when inserted into the computer (i.e. by setting in GNOME the appropriate command line in the "Removable Drives and Media").

A developer recently added a --play-cd option which does open Exaile and load the tracks, but you still have to select a track and then push play. Ideally, it would select the first track (or a random track if on shuffle) and play the CD automatically.

If you already have music playing, obviously it shouldn't interrupt you. Would make gnome-cd obsolete ;)

This ticket was migrated from the old trac: re #522
