morebits, config: new namespaces

Education Program is not really relevant to Twinkle (editing is restricted), so leaving it out of config.
config: update to new TOC object model
morebits: misc. amendments to QuickForm

- The custom event on radios and checkboxes now fires after the
  subgroup is created, meaning that the custom event has access to the
  subgroup's controls
- And yes, the subgroup does need to be cloned!

These are in relation to an upcoming overhaul of twinklespeedy.
