Bug 86011 [Wizards] Need to support creating multiple folders at once
It is currently not possible to create more than one folder at a time using the New folder wizard like it is with the import dialogs for instance. We would need to change ResourceAndContainerGroup so that it accepted paths in validateResourceName() and WizardNewFolderPage to build these.

* In normal usage, this method is invoked after the user has pressed Finish on
     * the wizard; the enablement of the Finish button implies that all controls on
     * this page currently contain valid values.
     * </p>
     * <p>
     * Note that this page caches the new folder once it has been successfully
     * created; subsequent invocations of this method will answer the same
     * folder resource without attempting to create it again.
     * </p>
     * <p>
     * This method should be called within a workspace modify operation since
     * it creates resources.
     * </p>
     *
     * @return the created folder resource, or <code>null</code> if the folder
     *    was not created
