VESPERS: Small changes to the group boxes in VESPERS2DScanConfiguration and VESPERSEnergyScanConfiguration.  They now disable the none for XRF and XRD detectors, respectively.
VESPERS: Tested the exporter for both Mar and Roper CCD's for the VESPERSEnergyScan.  Files, filenames and formats all appear correct.  Provides some progress to #324.
VESPERS: Changed the offset for the roper from 0 back to -1 because the 0 was due to an EPICS bug.  Once the bug was diagnosed, I changed it back.  Part of #324.
