v3.0.0

Support for generic continuous mapreduce queries was added. That means that map reduce now also works on any generic log format. set-clause support and a function parser to the mapreduce query language and the 'logformat' keyword was added. This release breaks compatibility with DTail 2.x.x as the transfer protocol from server to client had to be adjusted. So please update both, server and client. Added more unit tests. Also, all external dependencies have been updated.

Example to print out most common log lines containing string ERROR:

select count($md5), $hostname, $line interval 10 group by $md5,$hostname order by count($md5) set $md5 = md5sum(maskdigits($line)) where $line contains "ERROR" logformat generic

TBD: Add documentation and examples of the new features added..
