function commerce_backoffice_pre_render_add_fieldset_markup in Commerce Backoffice 7

Move form elements into fieldsets for presentation purposes.

Entity forms use #tree = TRUE to keep their values in a hierarchy for easier storage. Moving the form elements into fieldsets during form building would break up that hierarchy, so it's not an option for Field API fields. Therefore, we wait until the pre_render stage, where any changes we make affect presentation only and aren't reflected in $form_state['values'].
