Reduce log output

If you have a well configured pixolution flow there should be no logging overhead. However, in some situations you want to reduce the logging output for particular classes. You can do so by setting a stricter log level for particular classes or even packages.

Note: Hiding log messages may hide potential problems!

Only log errors for the class de.pixolution.lucene.search.WrappedScorer:
