We should have another option for autotagging beyond 'always preview' and 'always import'.
(respecting the beets config threshold values should be the default)

[x] trigger an import session after a preview session is above threshold. -> backend.
[x] better tag-grouping. this requires a group beyond 'inbox' something like 'to review' -> #26
