1) restructured GermaNetWrapper:
	getRulesForLeft/Right(leftlemma, leftpos, rightlemma, rightpos, GermaNetRelation) is now the basic function
	-> all other getRules... methods call it
	getRules... methods are also callable with Canonical Relation (Non-)Entailment
2) fixed antonymy handling in GermaNetWrapper
	when calling getRules...(..., has_antonym) antonymy rules are returned
	they are not included when retrieving rules for entailment relations
	their default confidence is 0.5, in config file 0.0
	0.0 confidence scores are not anymore excluded from results
3) included Named Entities in GermaNetWrapper
	Named Entities are labelled with "NP" pos tag
4) added another two methods for GermaNetRelation
	they allow a mapping to the GermaNet API's ConRel / LexRel
5) updated GermaNetWrapperTest
	includes tests for antonymy
	tests all callable methods for all POS tags and relations
	tests the three ways of initiating GermaNetWrapper
6) updated GermaNet configuration in config file
	confidence score in config file for antonymy is 0.0
7) updated to GN version 8.0
	changed version in pom.xml
	changed paths in test classes and GermaNetWrapper (local paths)
