[smila-dev] Refactoring of Lucene integration

[<Daniel.Stucky@xxxxxxxxxxx>]

Hi all,

I did some refactoring of the Lucene integration, mainly usage of
highlighting.

The following bundles were removed:
- org.eclipse.smila.transformation
- org.eclipse.smila.transformer (functionality may be added later
through Pipelets)

Bundle org.eclipse.smila.transformation.highlightingtransformer was
renamed to org.eclipse.smila.search.highlighting
It contains a HighlightingService (ProcessingService usable in a
Pipeline) and HighlightTransformer implementations.

Highlighting is no longer configured in the DataDictionary.xml but
through search parameters. See SmilaSearchDefault.xsl for an examples.

Bye,
Daniel
