LP1992490-Bootstrap Opac: sr-only, aria-label, and title localization.

Corrects some instances of non-localization of sr-only fields, aria-labels,
and title attributes.  Also corrects some stray display strings that were
not localized.

To test:

Apply the patch, and view each page to see if it renders. View the page
source of each page to see if the sr-only fields, aria-labels, and
title attributes are rendered correctly.
