Revert "Cleanup of Libraries, replaced global libraries with project libraries"

This reverts commit e44c04ad9dcf9b3e72c862a6002d29407be42fa3.
Quick & dirty fix of dependencies after an inexplicable fatal DOM parser clash (org.apache.xerces.parsers.SAXParser cannot be cast to org.xml.sax.XMLReader) I couldn't get rid of even after rolling back the latest commits. I had to clear the Maven repository and internal IntelliJ caches to get rid of that Exception. Unfortunatly some jars got lost along the way and were nowhere to be found through Maven, so I had to rebuild dependencies. Now all jars needed by the plugin are in one directory. This should be optimized some time soon.
Reorganized dependencies once more because of XML parser conflicts
New module: manifestgenerator, integration in the OpenCms plugin
