Changed the DatagramSocket constructor to use the lookback address to bind on. This fixes an issue on Windows systems where the DatagramSocket.close() takes 3000 ms to unbind when connecting to a non exisitig or disabled graylog server in the same subnet.
Removed * import.
Changed the default GELF messageIdLength to 8 according to the GELF 1.0 specification (https://github.com/Graylog2/graylog2-docs/wiki/GELF). Only set the graylogServerVersion to 0.9.5 to use the legacy GELF format.
