Add Menuitem "Edit" to player playlist contextmenu

[zdogde]

Hi theli, I downloaded your actual trunk version of listen and I think the actual player-playlist should also have the "edit" menuitem in the context-menu.

So I created a patch to add it. The patch is attached and should easily merge into your code. If something is wrong, please write me back :)

I now plan to contribute recently to your project :)

greets, zdogde
