Custom checkout/cart total renderers

If you need use a custom total renderer in some place (onepagecheckout for example), you can change the renderer template using local.xml directives.

<reference name="checkout.onepage.review.totals">
	<block type="tax/checkout_subtotal" name="subtotal_total_renderer" template="tax/checkout/subtotal.phtml"/>
	<block type="tax/checkout_shipping" name="shipping_total_renderer" template="tax/checkout/shipping.phtml"/>
	<block type="tax/checkout_discount" name="discount_total_renderer" template="tax/checkout/discount.phtml"/>
	<block type="tax/checkout_tax" name="tax_total_renderer" template="tax/checkout/tax.phtml"/>
	<block type="tax/checkout_grandtotal" name="grand_total_total_renderer" template="tax/checkout/grandtotal.phtml"/>
</reference>

It's important to provide correct block names such us subtotal_total_renderer.
