* Implements selection of a playlist item in the wizard

* The playlist in the wizard had to be displayed as a outlineview if we want to reuse existing code
* cosmetics could still be improved regarding this outline view
* I get this error

2005-07-24 00:08:55.940 VLC[6908] Could not connect the action t3_addressEntered: to target of class VLCWizard

When opening the wizard. I don't know if I messed up something or if it was already here before

* I needed to make some changes to the interface structure regarding the playlist for this : We know have a VLCPlaylist and a VLCPlaylistWizard class. Both are derivated from a VLCPlaylistCommon class that contains methods required by both classes (mostly the datasource, in fact).
