The "undo_function" part of callbacks was required, even though it
might not be required for functionality... Make it optional, so we
don't end up making/using no-op functions to avoid doing anything.

Also updated the testing scripts to support different configurations, as well
wrote tests for all the implemented hooks. This requires the latest version
of Tuque so be sure to update.
