Bug 7554: Clean newlines in browse script

Bug 7554: Clean newlines in browse script

Records with a newline in the title will break the Javascript search pagination
on the OPAC without this patch.

To test:
1. Import a record with a newline in the title (an example is attached to this
   bug)
2. Do a search that turns up the record and at least one other
3. View the detail page for one of the other records
4. Observe that there is a javascript error
5. Apply patch
6. Repeat search
7. Observe that there is no javascript error
