408042 removed advanced add-to-working-set import options

Advanced add-to-working-set options are now redundant.

Most users will want to create single project-specific
working set, which is now possible with single checkmark.

For the few users who want most elaborate working set
organization, there is 'add-to-working-set' dialog now.
