New features

• Better algorithm for removing duplicate messages. You can also run The Bat! with various command line options to ignore several message attributes while comparing messages: /DEDUPIGNOREMSGID (ignore Message-ID), /DEDUPIGNORETO (ignore To), /DEDUPIGNOREDATE (ignore Date), /DEDUPIGNORETOMSGID (ignore To and Message ID - this command line option is reserved for past compatibility). You can combine multiple command line options mentioned
