85c42216ab db: Give Playlists extra properties
* 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.

6eec4dbfc3 db: Add Track support to Playlist Tables
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.

1b9458c278 db: Add Track support to Playlist Objects
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.

8a9c90a7ff db: Add a base class for Playlist Tables
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")

d22b3c0ce2 db: Add a base class for Playlist Objects
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.
