Make sure QRegister::view is properly initialized and cleaned up

 * it must be initialized after the UI (Interface::main), so I added
   a View::initialize() function
 * the old initialize() method was renamed to setup()
 * use a global instance of QRegister::view so it is guaranteed to
   be destroyed only after any QRegisters that could still need it
 * Document API adapted to work with ViewCurrent references
