  • Complete internal handling for "shrink block". See #7 (more or less).
  • Add "breadcrumb" navigation fragments to split/shrink prep and do pages
  • Add link to pool IP list on edit and split/shrink prep pages
  • Shave off some useless code showing the split results
  • Catch the theoretically impossible case of "no subact value" on submitting split/shrink form

Still need to add calls to monkey rDNS on split/shrink changes
