[Banshee-List] Copying playlist to clipboard

[Tuukka Pasanen <tuukka pasanen ilmi fi>]

 Hello!
In songbird there is option to copy your Playlist to clipboard. So 
clipboard contains your song information what you see in screen.
That would be nice feature for banshee (as songbird dropped linux). I 
could implement it if someone shows little bit help.
