Added a field _pipelineName to AutoEvaluationPipeline. This allows to implement AutoEvaluationPipeline::getName() so that AutoEvaluationPipeline is no longer abstract. Consequently, the LuaPipeline is no longer needed.

This change was also used to change the AbstractPipeline constructor signature to pass-by-reference instead of pass-by-pointer for the pipeline's DataContainer. This presents the semantics more clearly since the DataContainer must not be 0.

PipelineRegistry and ProcessorRegistry are now part of campvis-core. Furthermore, moved all calls to PipelineRegistrar<>/SmartProcessorRegistrar<> to a separate cpp file for each module. This way all registrations are at one central location and including headers in external projects does not lead to double registration.

This commit also removes the obsolete columbia and manualsegmentation modules.

Cleaned up CMake scripts and added correct export definitions so that now CAMPVis can easily imported into other CMake projects through FIND_PACKAGE(CAMPVis).

Fixed module CMake files not setting ThisModShaderDirectories correctly in case of multiple directories.

Cleaned up DevilImageReader to be working with all kinds of input images and being completely OpenGL free.

* AbstractImageReader is now again an AbstractProcessor, so that we can get rid of the dynamic_casts in GenericImageReader
* DevilImageReader is no longer a VisualizationProcessor but gets the OpenGL context through OpenGLJobProcessor::ScopedSynchronousGlJobExecution
* Fixed alglib's CMakeLists.txt

[merged commit]clean ups, fixes for g++ errors and warnings, and edits for cppcheck errors (except for the 480+ in the external library AlgLib)

relocated mscopysegmentation module

relocated alglib library. Compiler warning level raised to w1 to get rid of float-double conversions.

save results into csv
akima spline interpolation using alglib, deleting nearest point

alglib library. extensive trimming required

ctrl+wheel zooming, arrow movement, ctrl+z, atl+click_nearest+click to edit _nearest point

multi object, multi location, multi slide contour point/line painting

draft code for addobject deleteobject

added ContourObject class linked with add and delete button.

added a proxy class of Vec4Property/Widget as colorproperty/widget to control drawing color

Conflicts:
	modules/vis/processors/sliceextractor.cpp

edited DevilImageReader to read multiple files having same name pattern: somePrefix_[number].[extension] given the 1st file name

Worked on DevilImageReader to load single 2d image for 3d rendering
