v3.0.0: drop2beets can import albums, too !

Thanks to @dtrunk90 the plug-in is now able to import single files as singletons (as it was before), but also complete folders as albums.

⚠️ current users should update their configuration. Please set these new properties:

    dropbox_paths:
        default: ~/beets-dropbox/albums
        singleton: ~/beets-dropbox/singles

This version deprecates the former dropbox_path property, that will be interpreted as singletons' path if it is the only one present.

v2.1.0

This release updates drop2beets dependencies and packaging system. It is functionally identical to v2.0.x
