fix for STANBOL-1342: The Entity Co-Mention engine now uses a ServiceTracker for LabelTokenizers; In case the LabelTokenizer is not able to tokenize the selected text of a TextAnnotation it will be ignored (not considererd for co-mention detection); Minor: removed the custom ServiceReference Comparator from the MainLabelTokenizer as ServiceReference is anyway compareable
