piano: Move to JSON API (v5)

In random order: Thanks to Chris Eby for his work on pithos, to an
anonymous coward for sending me his Android client, to Alex Howard for
sending me the webOS client, to ZigZagJoe for providing a temporary fix
and thanks to everyone who sent Pandora a message.

Although there are a few rough edges here and there this fixes #236.
