+order: Array of methods to check for OEmbed data. Methods include 'built-in'
+ (use a built-in function to simulate oEmbed for some sites),
+ 'well-known' (use well-known public oEmbed endpoints),
+ 'discovery' (discover using <link> headers in HTML), 'service' (use
+ a third-party service, like oohembed or embed.ly. Default is
+ array('built-in', 'well-known', 'service', 'discovery'). Note that very
+ few sites implement oEmbed; 'discovery' is going to fail 99% of the
+ time.
