* 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)

Refactoring pipeline concept #5: Moved Pipeline registration to modules module and gen_pipelineregistration.h which will soon be generated by CMake.

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

 * Pipelines evaluate themselves
 * removed the PipelineEvaluator
 * adapted all demo pipelines except OpenCLPipeline

=== 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
 * Updated all processors and pipelines to use ImageRepresentationXYZ instead of ImageDataXYZ and the implicit conversion feature

* fixed TransferFunctionProperty signal connections not working after assigning new TF

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!

 * introducing TumVisApplication for easy and straight-forward setup of pipelines, contexts, evaluators, etc.
 * VisualizationPipeline must not get its canvas during construction anymore

 * introduced Qt-threading based tgt::QtGLContext, tgt::QtThreadedCanvas and tgt::QtThreadedPainter
 * adapted tumvis-core and tumvis-application to new OpenGL context handling

Major revisions to the class layout / data structure:
 * Introduced ImageDataConverter interface (still not really happy with the design)
 * Removed support for Int64 and double images from WeaklyTypedPointer
 * Added ImageDataGL::bind()
 * AbstractProcessor::init() method, gets called by AbstractPipeline::init()
 * added VisualizationProcessor

Updated/New processors:
 * fixed MhdImageReader
 * SliceExtractor stub for very simple slice rendering

Various fixes:
 * DataContaier: managing of DataHandle ownership
 * GenericImageDataLocal::getSubImage()
 * ImageDataRenderTarget bindings
 * GenericProperty
 * linking issues with StringUtils

Hence, all this enables the first usable implementation of a specific pipeline:
The SliceVis pipeline combines MhdImageReader and SliceExtractor for a very simple 2D slice rendering
