Templates broken with ckan 2.1 / master

The harvest templates need updating to work properly on 2.1. There are obvious misalignments like on the listings page, but others more subtle like the admin button not appearing because the `actions_content` block has been removed from core (this one is a bit annoying, important blocks like this one should be kept backwards compatible somehow in core).
