Suggestion for Songbird Windows Explorer integration

I think Songbird should have full Windows Explorer integration.

That would be:
- Right click in a file or folder and select a new menu item: "Play in Songbird". A custom (or current playing) playlist should be generated to play just the selected files/folders.

- Double click on a file to play it in Songbird (file association).

Maybe other menu items could be added through customization:
- Add to Songbird library --- To add the selection to the library.
- Remove from Songbird library --- To remove the selection from the library.
- Find in Songbird library --- to open Songbird and find the selection in the library.
