Sam Hemelryk 4886029cba backup MDL-22142 Several changes to the backup UI and it's classes as noted below
*  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.
