Update to SBA section now supports customid of potteryhouse's version of SBA

Added functionality to support potteryhouse's version of SBA, which may also open operation to a few other
SBA versions.  This specifically added the customid to the export/import.  Other fields remain to be considered; however, the SBA is still in a state of flux.  Also updated some of the SBA related functions to support ZC 1.5.3. as they were not updated previously.
