✓ port: initial port
✓ fix: JS code cleanup (remove hardcoded hacks)
✓ fix: title + description (i.e. something's off with the theme wrapper)
✓ fix: #value_callback may be necessary? (see file.module) OR: ensure #return_value works
✓ fix: #element_validate callback: _hierarchical_select_validate() — verify this still works
✓ port: support multiple HS on the same page
✓ port: admin UI
✓ port: "dropbox" support
✓ upgrade path: delete cache_hierarchical_select
