Bug 35068: (follow-up) Update button order and icons

This patch updates the Renew and Check-in buttons so that they have
icons matching the ones used for the Renew and Check-in search tabs in
the header.

The patch also moves the Renew button so that it is next to the Renew
all button. I think this makes more logical sense. So the order is:

- Check in selected items
- Renew selected items
- Renew all
