Bug 7892: Open link to imported record in new tab

Change links to imported records to open in a new window/tab
on the staged records management page.

To test:
1) Go to Tools > Staged MARC record management
2) Open an imported batch by clicking on the file name
3) Click on bib# in the record column
4) Verify links open in a new window/tab now
