Autosave Playlist

It would be really nice if there was a setting to enable the autosaving of the currently open playlist, whenever the playlist is modified and/or when VLC is closed.

Similarly, if the currently open playlist was changed, a prompt asking if the user would like to save the changes to the playlist would be nice as well. In this case, there should also be a setting for the user to request to never be asked this, since prompts can be annoying to some users, but useful to others.
