This class combines a header with an initially hidden ListView that can
be configured to list our playlists. It also implements
"playlist-activated" and "playlist-selected" signals to signal user
interaction.

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")
