* added computation of difference image to SimilarityMeasure
 * fixed possible out of bounds access in datacontainerinspectorwidget.cpp
 * added assertions to ImageRepresentationGL constructor

removed preprocessing dependency from vis module (former dependency was only due to some deprecated code)

Fixes -Wswitch

Refactored DataNameProperty: Got rid of issueWrite() and connect(). Automatic invalidation of connected (shared) DataNameProperties is now delegated to AutoEvaluationPipeline.
ATTENTION: needs TBB 4.2 (not yet in repository, will be changed later)

Instead of having the LQ mode tied to the pipeline, each VisualizationProcessor has now a lqMode property effectively halfsampling the viewport size. The TrackballNavigationEventHandler was adapted to these changes and thus simplified.

work on #135: changed VisualizationProcessor::_renderTargetSize to pointer and introducing VisualizationProcessor::setViewportSizeProperty()

Revised event handling system: Got rid of campvis::AbstractEventHandler and replaced with functionality of tgt::EventListener and tgt::EventHandler

=== ATTENTION: CAMPVis does compile, but image representation conversion not yet functional again! ===

Revising ImageData concept step 2:
 * Removed all ImageDataXYZ classes
 * Introducing GenericAbstractImageRepresentation<T> and its GenericAbstractImageRepresentation<T>::ScopedRepresentation

The modules package is now itsself modular. Every subdirectory in modules/ builds its own submodule that can be individually switched on and off. Therefore each submodule needs its own submodule.cmake file to specify the build targets etc.
This is neat!

It took quite some time, but this commit introduces thread-safe management and access to multiple OpenGL contexts.
 * added tgt::QtContextManager for managing multiple OpenGL contexts
 * adapted tgt::GLContext and tgt::QtGLContext, tgt::QtThreadedPainter
 * added PipelineEvaluator for evaluating pipelines in separate threads
 * added various lock/sync features to processors, pipelines, and processors

However, there's still plenty of clean-up work to do: some parts of the tgt library are quite messed up and the core library interfaces need some polishing...
