[Muine] Patch to add DND importing

[iain <iain prettypeople org>]

Hi

Attached is a patch against CVS HEAD that adds the ability to drag a
folder into the Muine main window and have it be imported into Muine.
I'm not totally sure how the best way to do this fully would be, should
there be a "This folder needs to be imported, Yes, No" dialog, or should
it just automatically import like its doing now? Should the newly
imported files be added to the playlist?

There's also a change that I find very useful and it adds a "# of
tracks" text to the Play Album window, which shows how many tracks there
are in each album. Maybe only I find it useful because I have albums
where I didn't rip all the tracks.
