Bug 12403 [Follow-up] Batch record deletion

This follow-up makes several changes to language and markup with one
change in behavior:

- Updated permission description to avoid the use of the term "biblio"
- Updated batch delete template to avoid the use of the term
  "biblio" and to improve clarity.
- Replaced instances of terms "issue" and "reserve" with "checkout" and
  "hold" respectively.
- On bibliographic record batch delete, wrap biblionumber in <label>.
- On bibliographic record batch delete, show subtitle via Keywords to
  MARC mapping.
- On bibliographic record batch delete, respect BiblioDefaultView system
  preference.
- In the staff client cart, move batch delete link from "Action" menu
  to text link below (alongside "add to list" and "place hold"). The
  buttons are actions which affect the whole Cart. The links are actions
  which can be applied to selected items. I think this change makes it
  more consistent with the kind of operation being performed.

To test:

- Submit a batch of bibliographic records and confirm that the
  list of titles shows subtitle data as defined in Keywords to MARC
  mapping. Confirm also that the title links respect your
  BiblioDefaultView system preference.

- Perform a catalog search, select several titles, and add them to the
  Cart. Open the Cart and test the "Batch delete" link with and without
  titles selected. Test as a user who lacks batch biblio delete
  permission and confirm that the link does not appear.

Work as described, no koha-qa errors

I love the rewording, we always translated 'biblio' as 'bibliographic record',
it makes a lot of sense.

Tested using direct input of biblionumber or cart, subtitle display shows
correctly, link respect preference, user without permission cant acces the
tool or links.
