* backup moodleforms for specific stages are now cached between stage processing and display making it possible to leave all validation up to the bridge.
* The backup stage now relies entirely on the backup controllers save, load, and check methods + dependency checks rather then previous stage processing to ensure accuracy.
* filename is now a required field and validated to ensure it ends with .zip and is a valid filename.
* There is now a previous button for backup stages after the initial and before the complete.
* The progress bar previous stages are now links as well allowing the user to jump to previous stages (not linked on complete of course).
* The root settings are only shown on the schema stage now if they were changed because of dependency.
* Stages are now numbered in the progress bar.
* The complete page now shows a notice that the backup was complete and provides a continue button to view the backup file.
* Adds administration blocks to the backup pages.
