Return instance of WP_Query instead of post array in find_related()

[Slamik]

I propose to return WP_Query instance in find_related function instead of post array.

It's more native to Wordpress code style and developer can use standart loop in template or pass WP_Query instance to custom templater class.

Seems like an interesting idea but this would break backwards compat.

To no to brake backward compatibility you can add an optional parameter.
For example:

	public function find_related( $post_id, $return = 5, $instance = false  ) {
		$args = array(
			'more_like'           => $post_id,
			'posts_per_page'      => $return,
			'ep_integrate'        => true,
			'ignore_sticky_posts' => true,
		);

		$query = new WP_Query( apply_filters( 'ep_find_related_args', $args ) );

		if ( $instance )
		    return $query;

		if ( ! $query->have_posts() ) {
			return false;
		}
		return $query->posts;
	}
