Add include to command.php so WP-CLI commands are registered

#504

This solution doesn't work.

Fatal error: Class 'WP_CLI' not found in /srv/www/prism/htdocs/wp-content/plugins/posts-to-posts/command.php on line 3

Not sure how best to do this, will think it over.

Change this to:

if ( defined( 'WP_CLI' ) && WP_CLI ) {
    require_once dirname( __FILE__ ) . '/command.php';
}

[danielbachhuber]

You can also use command.php without the code change by doing:

wp --require=command.php p2p

Yeah that might be better. If I get the time I'll update the docs.

I added a class_exists check that works, but I'll leave it @scribu
