membership autorenew error when included via price set

to reproduce:

1. create a membership type and set auto-renew as required
2. create membership price set and include the auto-renew membership
3. create contrib page for memberships and assign this price set
4. visit the live contrib page

no auto-renew option or notification is included, and if the form is submitted, auto-renew is not triggered. if you view the console log, you will see the following error:
showHideAutoRenew is not defined

in templates/CRM/Contribute/Form/Contribution/MembershipBlock.tpl, around line 230, we condition the inclusion of the showHideAutoRenew function on whether the form is a quick config form or not. since a price set is not quickconfig, the function is not include in the page – but is called from the rendered form field. I suspect that js error trickles down and prevents the auto-renew option from getting set.
