Bug 20742: Update two-column templates with Bootstrap grid: Administration part 6

This patch modifies several administration templates to use the
Bootstrap grid instead of YUI.

This patch also removes obsolete "text/javascript" attributes from
<script> tags and "text/css" attributes from <style> tags in the
modified templates.

To test, apply the patch and view the following pages, confirming that
they look correct at various browser widths:

 - Administration -> MARC frameworks -> MARC structure -> Subfields
   - View and edit subfields
 - Administration -> Record matching rules
   - View and edit record matching rules
 - Administration -> OAI sets configuration
   - View and edit OAI sets
     - Define mappings for an OAI set
 - Administration -> Patron attribute types
   - View and edit patron attribute types
 - Administration -> System preferences
 - Administration -> Z39.50/SRU servers
   - View and edit servers
