Bug 19653: Move tools templates JavaScript to the footer: Additional tools

Bug 19653: Move tools templates JavaScript to the footer: Additional tools

This patch modifies the staff client "Additional tools" templates so
that JavaScript is included in the footer instead of the header:

- Calendar
- CSV profiles
- Log viewer
- News
- Task scheduler
- Edit quotes for QOTD feature
- Upload

Note that the log viewer template has been modified so that the
"interface" variable (passed to the template to provide the correct path
to staff client assets) isn't overwritten by an "interface" variable
required by the log viewer.

To test, apply the patch and test the JavaScript-driven features of
each modified template: All button controls, DataTables functionality,
form validation, etc.
