Bug 30474: Convert tools pages tabs to Bootstrap (part 1)

This patch converts jQueryUI tabs on three tools templates to Bootstrap
tabs.

To test, apply the patch and go to Tools -> HTML customizations.

- Click "New entry."
- On the entry form you should see two tabs, "Default" and "English
  (en)"
- The tabs should look correct and work correctly.

Go to Tools -> Batch record deletion.

 - Test the three tabs: "Upload a file", "Select a list of records", and
   "Enter a list of record numbers."

Go to Tools -> Batch record modification.

 -  Test the same three tabs on this page.
