Bug 33180: Use template wrapper for tabs: Budgets and Search engine configuration

This patch updates two administration templates so that they use the new
WRAPPER directive to build tabbed navigation: Budgets and Search engine
configuration.

Note: this patch includes indentation changes, so check the diff
accordingly.

To test, apply the patch and check the updated pages:

 - Administration -> Budgets
 - Administration -> Search engine configuration

On both pages tabs should look correct and work correctly.
