Bug 13218: fixing acquisitions z39.50 interface to be consistent with the others.

Bug 13218: fixing acquisitions z39.50 interface to be consistent with the others.

Changes:
* Two columns of search fields into one
* moves targets from below search fields to the right of them

To test:
* Create a basket in acquisitions
* attempt to add a record to the order from an external source
* note the changes to the layout
* complete a couple of additions to the basket - functionality should be unchanged.

If you like the changes, sign off :)
