Bug 21436: Update two-column templates with Bootstrap grid: Tools part 4

This patch modifies several tools 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:

 - Tools -> Task scheduler
 - Tools -> Staged MARC management -> View batch -> View diff of
   imported record which duplicates a record in the catalog
 - Tools -> Stage MARC for import
   - Test each step
 - Tools -> Upload local cover image
   - Test each step
 - Tools -> Upload any file
   - Test each step
 - Tools -> Log viewer
   - Test from the tools menu and from both the bibliographic
     patron details pages ("Modification log").
