Title: 84202472 turn off input echo by default

Addresses issue #4589

Since this is trying to minimize the writing to the audit file, it could not depend on a input in the IDF file so instead it is using environmental variable called "DisplayInputInAudit" that shows the input file in the audit file only when set to Yes.
