functions with unit tests: get_required_user_name_fields, get_enabled_user_name_fields,
get_disabled_user_name_fields.

If the language string is missing firstname or lastname, then when displaying the
user edit form it defaults to 'firstname lastname'

Previous logic has been moved out to new functions with unit tests.

The restore progress bars introduced a bug when restoring Moodle 1.9 backups.
build_plan needs to be surrounded with start_progress/end_progress with the mode
set to indeterminite or it throws coding errors.

Added a behat test for the creation and deletion of a new course.
This should turn up any such errors like this during automated
testing in the future.

Files bigger than 4GB is not supported at this point. Zip archiver doesn't know about it and always returns true. We need to verify if it is a valid file or not and delete if not
Also delete the backup file immediately if anything goes wrong anywhere in backup. We don't want to use up space
