This change adds the preserve option to the quartz method which makes it base the temperature adjustments on the existing gamma ramps when set. This requires that the existing gamma ramps are saved at start-up which this commit also adds. One drawback is that the list of displays is enumerated at start-up now which means that Redshift will likely not affect displays that are connected after start-up. This could be fixed in the future by listening to reconfiguration events.
