Hotfix/update2new dsx tone analyzer

[tjhgit]

DSX now runs on version 2.11.8 and scala 2.1.2. Also tone analyzer changed the return value since 2017.

1. use new versions in build.sbt
2. got rid of Logging -> only using log4j
3. JSONObject is now provided by different package

Tested this pull request as follows:

To compile it, use this command: docker run -it -v $(pwd):/root/src -p 4040:4040 -p 8080:8080 -p 8081:8081 -h spark --name=spark p7hb/docker-spark:2.1.1 when inside the above spark.samples directory.

Inside the docker container:

cd /src/streaming-twitter

sbt update
sbt clean compile
sbt console

sbt assembly

Runs flawlessly in sbt console, however leads to the following error on DSX:
