Tomcat

Restful service under Tomcat.

1) Created a new module (rest-tomcat) to store a "listener class", web.xml and config resources(log4j,server.properties);

2) Turned public some private methods in org.dbpedia.spotlight.web.rest.Server.java (setDisambiguators, setSpotters) and create a new one as public to set Spotlight Configuration ( setConfiguration(SpotlightConfiguration configuration));
Merge pull request #200 from sandroacoelho/tomcat

Refactoring in NIF 2.0 (Separation of concerns)

-Spotlight should to provide only the data. Now It (re)uses an external library that knows all details about NIF format
Solving prefix/full uri bug

- It is not correct concatenate DBpedia ontology prefix when a type is a vocabulary specification (e.g foaf:Person)
- For a small string, it is enough (and memory-oriented) to use .concat method instead of create a StringBuilder
Merge remote-tracking branch 'origin/NIF2.0' into NIF2.0
