osishtmlhref and osisxhtml does not handle <div type="x-p">

Chris Little changed osis2mod paragraph handling in r3011. Previously <p>...</p> was transformed from <div type="paragraph" sID="xxx"/>...<div type="paragraph" eID="xxx"/> to <div type="x-p" sID="xxx"/>...<div type="x-p" eID="xxx"/>.

The filters osishtmlhref and osisxhtml have handling for the former and not the latter. They now need to handle both type="paragraph" and type="x-p". Both for the sake of backward compatibility with modules that have already been released.
