This applies to both the Table and child Playlists models. I'm doing my
own idle handling already for searching, so we can rely on that instead
of needing Gtk to do it. The benefit to this is that we can select
playlists programmatically during startup, since we don't need to worry
about the Table not being fully loaded yet.

This is used to notify the model that the rows have changed when it's
not automatically being detected. I first noticed this when attempting
to disable incremental filtering, due to the Artist list not getting
refiltered when new child Albums were added to the Artist.

I combine this with the table's Filter object to show playlists matching
the current search query.

It defaults to a None pointer, but calling add_children() will set one
up with an empty set. I also implement functions for adding, removing,
and verifying child playlists.

* loop is based on the mpris loop property, and can be set to "None",
"Track", or "Playlist".
* shuffle is a boolean True / False value.
* sort-order saves a user-configured sort order for each playlist.
* current-trackid is an integer referring to the trackid of the currently
playing track.
* user-tracks: is a boolean representing if the user should be allowed
to manually add and remove tracks.
I also use the sort-order property to implement a get_track_order()
function to get the sort keys for tracks in a Playlist.

I implement add_track(), get_trackids(), and remove_track() functions that
either modify the 'system_playlist_tracks' table or call a virtual function
depending on the value of the 'system-tracks' property.
I also add the "autodelete" property. When set to True, Playlists will
be deleted when they have 0 tracks remaining.

Playlists use a tracks.TrackidSet to manage a set of trackids
representing the Tracks in this Playlist.
I have two functions for loading tracks: load_tracks() and
reload_tracks(). Calling load_tracks() checks if the tracks have been
loaded first before doing any work, but calling reload_tracks() will
force the Playlist to go to the database to load the latest tracks.
Finally, I add a have-next-track property to the main database
connection. This is set to True whenever the active playlist has one or
more tracks.

This is an implementation of an emmental.db.table.Table that adds
support for creating Playlists, updating playlist properties, sorting
based on playlist name, and displaying playlists with their child
playlists in a tree structure.
Additionally, I create a playlist_properties table in the database to store
properties that all playlists have.
Implements: #17 ("Save currently selected playlist")

This object inherits from the table.Row base class. It adds in
properties for name, active state, and propertyid and a rename()
function for updating the Table sort order during a rename.
Additionally, child playlists can be enabled by calling add_children().
This will set up a Gtk.FilterListModel using the provide child Table and
Filter.
