Fixed issue 06478: Unable to import excel survey
Dev Removed dependency upon excel_reader; instead read/write to tab separated value (.txt) file
Dev This works fine in the 1.92 extension.
Dev However, this still can has trouble (like with accents) in 2.0; but since the code changes are identical in 1.92, the source of that problem must be elsewhere (perhaps in the model->insertRecords() functions?)
