bump up version to 3.0.0. can run continuous background mapreduce queries, useful for log file monitorig for example. breaking protocol change which allows to mapreduce aggreate messages containing the default field separator |. add of more unit tests. add logformat mapreduce query keyword. add set mapreduce clause support and support to evaluate built-in functions such as md5sum() and maskdigits().v3.0.0
