Title: Add option to automatically attach inline images in HTML email messages

Added 'inline_images' and 'image_path' preferences. Changed 'attach' function to return Content ID with new '_get_content_id' function when disposition is 'inline'. Changed '_build_message' function to automatically attach inline images if preferences are set.
