When a track finishes, I tell the library to update playcount. Then,
the library triggers a callback to the playqueue deck telling it to
update.
This patch also finds and prints the track that causes a gstreamer
error.

When the count is changed or pausing finishes, I trigger this callback
to notify the UI. I also added in a line to enable pausing any time the
count is incremented.

I implemented an entire Gtk::TreeModel in this commit, plus some minor
supporting code in the library to look up playlist entries by index.
