Online contribution page with price set: Payment method block should be hidden when total selected amount is $0

$0 contributions result in the billing block being hidden - but I think the payment selector should be hidden as well.

To test you need to enable more than one payment option & have a price set with a $0 option. When $0 is selected the billing block is hidden but you still get to chose between credit card & pay later which I think it probably an over-sight rather than a design choice.

This is the code we are trialling (on 4.4 patched with CRM-14882)
