Align sandbox components with latest opennlp tools (snapshot) version (#153)

* adjusts sandbox to use latest opennlp-tools snapshot version for verification of recent changes
- adds logger to WSDEvaluator to avoid plain System.out logging
- clears some compiler warnings

* OpenNLP tools used slf4j2 -> adjusts log4j2 with slf4j2

* Fix opennlp-wsd (requires PENN format)
