Bug 16600 - Remove some obsolete references to Greybox in some templates

This patch removes unused Greybox markup from two templates.

To test, apply the patch and go to Authorities.

- Perform an authority search which will return multiple results.
- Select two records to merge.
- On the "merging records" page, an earlier version used Greybox to show
  a preview of the selected authority records. Confirm that authority
  number link for the two records triggers a pop-up window instead.

- From the authorities home page, choose 'New from Z39.50'
- Perform a search which will return multiple results.
- Confirm that there is only a 'MARC' preview link. A
  forever-commented-out 'Card' link has been removed.
