Use relative path to save playlist

[JohnCPun]

Make a playlist of various songs.
Save the play list.
Now copy the songs and playlist to another location.
Open the playlist.

The playlist can't open the songs as in the playlist a absolute path is stored.
It would be nice if the playlist would store a relative path, so the songs can be opened when copying like this.

For myself I see it mostly as being able to set up a playlist on my PC at home and then copy it to the laptop I have at the rehearsal space, which I use for live shows, etc. Right now I can't do that and have to make the playlist on the laptop I will be using live (or edit the path in the XML).

It might be related to #353

Actually , items on playlists can use relative paths. I use it in that way, but you need create/tweak your playlist manualy i.e. it works only for load, not for save.
I also added support for load song relative to Jack Session ( SESSION_DIR environment variable ).
( SongReader::getPath method in code ).
Maybe it should search for file also in directory where playlist is stored ?

Oh .. and I see that I added also support for save playlist during saving session ( JackSession ). It copy all songs to session directory and use relative paths on new playlist ;-)

Hm, maybe this should an option in the playlist dialog. If we would store only relative paths, i bet somebody comes around who wants to move his playlist around (on the same pc) and does not like relative paths in the playlist.

[JohnCPun]

Yeah, that is pretty much guaranteed :)
So making it an option sounds like the best way to go.

Hi,

this is now implemented. I've added an option to the preferences dialog which allows you to configure if the playlist uses relative or absolute paths.
