 * Finished implementation of empty space skipping
 * Renamed Adaptive Step Size to Intersection Refinement (which is more precise in terms of what it's doing)

 * Introducing BinaryBrickingVolume
 * Prototype implementation of computing the BBV lookup volume

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)

Even though many float-based properties derived from
FloatingPointProperty used the same step value, T(0.01), it had to be
specified when instantiating them. To reduce boilerplate code in
property constructors, FloatingPointProperty now uses T(0.01) as the
default step value.

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

A new attribute has been added to all numeric properties: step value. It
determines the value of a single increment/decrement that numeric
property widgets use when their associated properties are modified using
sliders or spin boxes (users are still able to type any valid property
value in text edits).

Numerous processors and pipelines had to be updated to work with the
changed NumericProperty interface. However, choosing a well-suited step
value for each property can make it easier for users to modify the
property — using one step value for all properties leads to cases where
it is either too small, causing users to go through property values
which don't cause any visible change, or too big, making it difficult to
quickly determine the right property value.

 * each VisualizationProcessor manages its own FBO
 * instead of creating a whole new FBO each process(), the processors shall only create and attach textures to the FBO
 * the FramebufferActivationGuard offers automatic (de)activation and detachment of all textures

SimpleRaycaster already uses the new concept, the rest still uses the legacy API

further step to OpenGL 3.3 core compatibility in core and modules: Got rid of glPush/PopAttrib in processors, added asserts for correct OpenGL state after processor execution

Revised InvalidationLevel concept: InvalidationLevels now directly belong to an AbstractProcessor and are considered to be thread-safe. Furthermore the different levels now really act as single flags that are set (invalid) or unset (valid) individually.

=== 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

Work on SimpleRaycaster to implement adaptive sampling and intersection refinement, still some work to do though...

* some refactoring of property names

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!
