DBpediaCrawler: fetching only rdfs:label for locations
DBpediaCrawler: removed shows from crawling for now; removed testing limitations from queries
DBpediaCrawler: tried to implement type checking but it is still buggy, so no type checking per default
Merge branch 'master' of https://github.com/nicolas-fricke/semmul2014
DBpediaCrawler: use global options folder (added dbpedia.yml, some options from namespaces.yml overwrite settings); pushing URIs of fetched entities to queue raw_dbpedia from namespaces.yml
