Comment 1 for bug 1526163

I have pushed a commit here http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/bhorn/LP1526163-checkout-auto-renew-not-honored

It adds a check during checkout for the auto renew policy and also adds a check to make sure the items out count doesn't increase if the current transaction is a renew.
