Unfriendly "Please move your music to [dir]" message on first startup

Binary package hint: banshee

In a fresh 11.04-dev install, Banshee's first message was, in white on black:

    "Please move your music to /home/sander/Muziek"

For several reasons I think this is not a good welcome:
- the user may not have any digital music yet, so there is nothing to move,
- the user might not be familiar with the forward-slash directory notation, which is hidden well in other GNOME apps,
- the user may have reasons to put music in another directory, and then "File > Import Media" is a better option.

Some suggestions for improvement:
- adding a "Import Media" button in the main screen when the library is empty,
- starting in the Ubuntu One Music Store,
- adding a way to open the ~/Music directory in Nautilus, so that the user can easily drag-and-drop music files.
