 Saves all TWinControl-descendants of all Pages of a PageControl in a stream 
 can easy be used to save userdefined Options 
 Place a new control to the PageControl and it will be saved to the stream, without 
 any additional codeline 

 Speichert alle Abkommlinge von TWinControl auf allen Seiten eines PageControls 
 in ein File 
 Erleichtert das Speichern von benutzerdefinierten Optionen 
 Einfach ein neues Control auf das PageControl setzen und es wird ohne zusatzlichen 
 Code gespeichert
