CONDEC-1028: Improve decision grouping, automatic text classification, and change impact analysis (#699)

* Fix that decision grouping did neglect the project of a knowledge element

* Update dependencies in pom.xml

* Make change impact coloring more subtle

* Implement Naive Bayes classifier

* Reduce size of training data for support vector machine to avoid out of memory exceptions

* Add data center compatibility

* Update version to 2.3.7
