Bug 7607: (follow-up) Address OPAC and limits

Bug 7607: (follow-up) Address OPAC and limits

This patch adds the same function to the OPAC and adds support for limits

I adjust the class on staff side to match the one already existing on OPAC

On the OPAC when you click the back button the fields are not enabled - on the staff side they are,
I leave this problem for someone else to solve
