Bug 10691: use authority ID in see-also links in authority search results (staff)

This patch changes the URL and data used to show the 'see also' links
on the Staff'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 entries with plain text (i.e. no
  linking)
- Make sure zebra is running and changes got indexed.
- In the staff interface 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 for linked
  authorities,
  and to an authority search result in the case of plain text entries.
- Check that the authority search from the cataloguing interface still
  works as usual.

Bug 10691: use authority ID in see-also links in authority search results (OPAC)

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 headings.

Bug 10691: (follow-up) restore behaviour for control field ($w)

As noted by Jared, in the presence of 4XX$w or 5XX$w the display
got broken by this refactoring. This patch restores the previous
behaviour in that front.

The OPAC themes get fixed too, and the Bootstrap one gets this
fix too.

Applied the fix that Galen proposed on comment #30 regarding
Zeno's fix in bug 11174.

Bug 10691: (follow-up) replace HTML comments with TT contents

Comments on the usage of Template Toolkit blocks don't need
to appear in the rendered HTML, so this patch converts HTML
comments to TT comments and thereby saves a tiny amount of
bandwidth.
