Bug 10691: 5xx not properly linked by authid in authority search result list

Bug 10691: 5xx not properly linked by authid in authority search result list

This patch changes the URL and data used to show the 'see also' links
on the OPAC's authority search results page.

Bonus points: makes some strings translatable.

To test:
- On your dev setup (master) create some authority records (i created personal name authorities).
- Pick one of them and link 400$a to another one, do the same with 500$a
- Add some other 400$a and 500$a without linking (i.e. plain text)
- Make sure zebra is running and changes got indexed.
- In the OPAC search for the authority that is linked to the others.
- Check the 'see also:' link points to an authority search
- Apply the patch
- Reload/re-do the search
- Check the 'see also:' link points to the authority id in the case of linked authorities,
  and to an authority search in the case of plain text names.
