Back by popular demand: results in wide format for SPSS

Wide output format for results and credit questionnaires is back! We've re-engineered the format to cope with as many columns, and as much data as you can throw at it.

We've had to move to CSV file format to address a number of issues specifically related to the former XLSX version. This re-engineered format also introduces suffixes for trial procedures. See the wide format documentation for more detail.
