Price with tax inside product list

Hello,
There’s a problem when showing prices inside product list of a product, as they don’t include tax.

Line 1437 from v1.5.5 should be modified as:
echo '<del>' . wc_price( wc_get_price_including_tax($woobt_product) ) . '</del> ' . wc_price( $this->woobt_new_price( wc_get_price_including_tax($woobt_product), $woobt_item_price ) );
