EDXDController and EDXDMappingController changed for I08. Before the 
aquisition time was not setup because the method setAquisitionTime 
was empty in EDXDMappingController.Remove setAquisitionTime in 
EDXDMappingController. 
A new method setPresetMode and getPresetMode were added to set the 
preset mode through GDA.
