Modified DispQsos to set Qsl value to Tnx if Rcvd status is Yes,
otherwise set to Pse. Modified DispQsoTests to match these changes.
Modified user manual to remove the section in workingwithqsos.xml
that described the Qsl value returned based on Rcvd and Sent statuses.

These changes effectively remove the changes that were made for
issue #9. Issue #9 will have to be implemented in a different manner.
