Bug 22973: Remove type attribute from script tags: Staff client includes 2/2

This patch removes the "type" attribute from <script> tags in several
staff client include files. Also removed: Obsolete "//<![CDATA[ //]]>"
markers.

This patch also makes minor indentation changes, so diff using the "-w"
flag.

To test, apply the patch and confirm that examples of affected pages
work properly without any JavaScript errors in the browser console:

 - Installer -> Onboarding (uses installer-strings.inc,
   validator-strings.inc)
 - Patrons -> Patron details -> Change password (uses
   password_check.inc)
 - Patrons -> Patron details -> Print summary (slip-print.inc)
 - Circulation -> Check out (strings.inc, timepicker.inc)
 - Cataloging -> New from Z39.50/SRU (z3950_search.inc)

Validating the HTML source of any of these pages should return no errors
related to the "type" attribute.
