Committing updated version of the VisIt Java Client from NiCE

This is the latest version of the VisIt Java Client that builds in NiCE/the Eclipse ICE Initial Contribution. It is provisioned in a way that works with both MAVEN and the OSGi. Some small amount of branding may need to change, but it is otherwise good to go. 

I built NiCE using it successfully on my laptop and I just need to test it with Hudson. I don't expect testing it with Hudson will require any changes to the source.
