Bug 6574 - js error in en-GB and en-NZ translations due to improper quoting

To replicate:

* install en-NZ translation (or en-GB)
* activate the new language, and select it for use
* pretend you are going to issue a book to a member (search for a member from "check out" in header)
* without the patch, the toolbar will be incorrect. The toolbar will also be incorrect on moremember.pl.

To test:
* apply the patch
* re-generate the en-NZ or en-GB translation
* activate the new language, or select it for use
* pretend you are going to issue a book to a member (search for a member from "check out" in header)
* with the patch, the toolbar will appear to be correct. It will also be correct on moremember.pl.
