Discogs API v2 public client for PHP5.3

This is a small helper to retrieve public information from discogs.com using the API v2.

Actually, ther is only two functions implemented:

• Search for all releases
• Retrieves a release

Example:

$d = new Discogs("MyPersonalClient/0.1 +http://mypersonalclient.com");
foreach( $d->searchRelease("Zappa") as $id => $release )
	var_dump( $id );
var_dump( $d->release('2754221') );
