Draft: Save Binning, Fits filter settings (guider), Camera gain (solver) and

configure SEPMultistarOptions correctly

• added saving of guider binning and guider fits filter settings (with respect to the existence of a possible cam guider header)
• added saving of solver camera gain
• corrected checkboxconfig of autostar and subframe for 'SEPMultistar' mode in guide tab of EKOS (SEPMultistar always uses autostar and does not subframe)
