Bug 20736: Update two-column templates with Bootstrap grid, Administration part 1

Bug 20736: Update two-column templates with Bootstrap grid, Administration part 1

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

This patch also removes obsolete "text/javascript" attributes from
<script> 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 -> Budgets
   - View budgets list, view and edit budgets
   - View budget -> Planning -> Plan by months
 - Administration -> Funds
   - View funds list, view and edit funds
 - Acquisitions -> Vendor -> Contracts
   - View contracts list, view and edit contracts
 - Administration -> Audio alerts
 - Administration -> Authorized values
