I implement add_year(), remove_year(), and has_year() functions and make
sure we load the set of yearids during startup. Additionally, I have
Years add and remove themselves from Decades as they are created and
deleted.

I expand on the decades_view to include additional playlist properties,
and configure the default sort order to sort by year first.
I then set up the decade_tracks_view to make it easy to select tracks
that belong to a specific decade.

Similar to the Artists tree structure. I create a filter on the Year
table for each Decade object and adjust filtering so a Decade remains
visible if one or more years match the query.

This table allows us to work with Decade playlists that can be created
or looked up by an individual year in that decade. I also add a few
custom functions to SQLite to make working with decades easier.
