VESPERS: Fixed a small bug in the getUniqueFileName method for VESPERSScanController.  It was using the unmodified path and never looking in the correct location.  Also did a tracer round testing loading the Roper images into AM.  That will be refined during #387 and #388.
VESPERS: Reduced VESPERSRoperCCDDetectorInfo and VESPERSMarCCDDetectorInfo to a single class called VESPERSCCDDetectorInfo and made the necessary changes in the detector classes to get it to compile and run properly.  Fixes #386.
