Bugfix / enhancement: Prevent duplicate libraries

To prevent duplicate Libraries in build i had enhanced/corrected the excludes.

Actually ther were two  diferent versions of wodstox (ASF 4.1.4 / LGP 4.2.0) and two different commons-logging libraries (commons-logging/jcl-over-slf4j) 

In addition to that change i found out that the dependecy from batik-transcoder to fop has changed and the old exclude of fop:fop didn't work nowadays.

For reference here the dependency:tree output for woodstox/commons-logging:
