*  All "exclusion" patterns are now matched by regex.
*  Added StripPublishOption constant.
   If set to _True_ the following lines are also excluded from the export files
  * dbByte "PublishToWeb" ="1"
  * PublishOption =1

   The function tries to delete _FileName_ three (3) times before giving up.
   A delay of 100ms is introduced between delete attempts should the first fail.
