#117487, make sure root node gets created properly, and prevent changing priority when there are no adjacent tasks.

Updated version so it automatically gets entered by drupal's release script. Tweaked capitalization of name according to drupal standard.

Fixed issue with filter defaults being set improperly, and thus no tasks being shown until filter was manually applied.

Fixed redirect after changing order where it would go to the current user's tasks instead of return to the current page.
