Fix bugs 3528 and 3534 by Ozgur Ugras BARAN and myself:

* ControlToc::updateBackend(): emit Buffer::structureChanged()

* QToc:
  - updateToc(), updateType(), typeModel(): deleted.

* TocWidget
  - updateGui() manually with ControlToc::typenames()
  - on_typeCO_activated(): changed to on_typeCO_currentIndexChanged()
