Bug 33323: Select button in patron search modal is not translatable

Bug 33323: Select button in patron search modal is not translatable

This patch modifies the JS which generates some markup during some kinds
of patron searches so that the strings labeling submit buttons can be
translated.

To test, apply the patch and go to Administration -> Funds.
- Add a fund or edit an existing one.
- Test the "Select owner" link
  - A popup should appear, and after performing a patron search which
    returns results you should see a "Select" column in the last column
    of the patron search results table.
- Test the "Add users" link
  - Perform the same test as above. The button in the last column should
    be "Add"
- The template accommodates two other cases, "Edit" and "Check out" but
  I was unable to find a place where they were used.

- To test translatability, run the translation tool for any language,
  e.g.

  perl misc/translator/translate update fr-FR

  Search the regenerated po file (in this example
  misc/translator/po/fr-FR-staff-prog.po) to confirm that the
  correct strings are there: "Select", "Add", "Edit, and "Check out"
  should each have entries for line 234, e.g.

  koha-tmpl/intranet-tmpl/prog/en/includes/patron-search.inc:234
  c-format
  msgid "Select"
  msgstr "Sélectionner"
