Adapt AIDA light to support disambiguation of mentions (text annotations) extracted by Stanbol

AIDA-light original disambiguation service takes as input a text/plain content and returns as result a list of Mentions within the text. Each mention consists on the most prominent entity candidate in YAGO and a confidence value.

In Stanbol, those mentions are already extracted by the NLP engines and converted to TextAnnotations. Therefore, AIDA-light should be extended with a new service that would receive TextAnnotations and the original content as parameters and would return YAGO's candidates ordered by their disambiguation's confidences values for each TextAnnotation. Those candidates will be mapped later to Entity Annotations back in Stanbol
