Subject: scrobbler: watch for events and print song details

We create a module "mpd" to interact with our MPD instance. For now we
only have a single function to create a new client, which creates an
actual client for mpd (and we ping the instance every 30 seconds), and
a watcher to receive new events.

The tool "scrobbler" then wait for new events and display songs
information.
