Tons of dependency fixes and updates

* Removed unused JARs from org.simantics.scenegraph and re-exported
  org.apache.batik from there instead of including three old batik JARs
  internally to export the batik parser.
* Replaced all dependencies on org.apache.commons.collections with
  org.apache.commons.collections4
* Removed version specifiers from all org.slf4j.api and
  org.eclipse.collections.eclipse-collections* dependencies
  to avoid the need to modify them down the road with new major releases
* Explicitly specified all Jetty dependencies to be on version 9.4.24
  in an attempt to avoid OSGi (Felix) bundle wiring performance problems
  experienced by Marko in recent developments.
