Bug 13638 - Batch patron modification tool missing option to switch language

The batch patron modification tool's template was created without the
footer include at the bottom. Without the footer include the language
toolbar will not be displayed.

All page templates should include the global footer include:

[% INCLUDE 'intranet-bottom.inc' %]

To test:
 - Install at least a second language
 - Enable at least 2 languages (language system preference)
 - Go to tools > Batch patron modification
 - Verify that at the bottom of the page the language chooser is shown

Followed test plan. Works as expected.
