SVN commit 598090 by aoliveira:

* Save dynamic playlist items by their "path" (eg: "Smart Playlists/Collection/Favorite Tracks/By Pearl Jam"), instead of using 
only the name.
If we don't allow two playlists with the same name on the same folder, all our problems with playlists being misindentified will be 
fixed.
I bumped the version for dynamicbrowser_save.xml, and I still didn't write the migration code.

* While I was at it, adding and removing items to dynamic playlist is now recursive on Playlist Browser, for consistency with the 
Playlist Selection dialog.
