Add new reporter for machinally analysis

This **machineout** reporter will report any Fail or Error as format as
below::

    <Type>:<Method>:<File>:<Row>:<Column>:<Message>

So you can analyse the message with simply splitting the line with ":"
In python, the analyse method will be like below::

    def analyse_nodeunit(s):
        type, method, file, row, column, message = s.split(":", 5)
        return type, method, file, row, column, message
