[Plugin: JSON API] Empty comments array in post data (with solution)

Requesting a post through the get_post function of the API returned the correct number of comments, but the actual comment array was empty.

The introspector public function get_comments is named the same as the wordpress core function, so you used SQL, but that didn’t work. Using get_comments() within get_comments() causes a recursive loop.

I used a different wordpress core function called get_approved_comments():

public function get_comments($post_id) {
    global $wpdb;
    $comments = array();
    $wp_comments = get_approved_comments($post_id);

    foreach ($wp_comments as $wp_comment) {
      $comments[] = new JSON_API_Comment($wp_comment);
    }
    return $comments;
  }

I probably should have used an action hook, but I’m lazy.
