Fixing bug in CSV reports when function alterNickName

The return of function alterNickName (a string) 
includes a carriage return.  When that carriage return is converted 
to the CSV version of the report for download, the field 
then includes a carriage return, making 
it quite difficult to import and use this field in Excel.  In Excel 
the carriage returns come through as CHR(10) which is quite difficult 
to search/find/remove in an automated way.

The fix just breaks the string up so that the carriage return is 
removed and also so that future edits will be unlikely to
re-introduce it.
