Removing TBB library from /ext making it fully external (user has to install TBB himself). Adapted CMake files. Adapted include directions

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)

Refactoring pipeline concept #2: Got rid of distinguishing between AbstractPipeline and VisualizationPipeline. Every AbstractPipeline is also a VisualizationPipeline. However, AbstractPipeline does not care about evaluating its components - this has to be implemented in its subclasses.
AutoEvaluationPipeline subclasses AbstractPipeline and automatically evaluates the pipeline by listening to the signals of its components and calling the corresponding process() methods.

introducing AbstractProcessor::updateProperties(DataContainer&) which is automatically called by AbstractPipeline when a processor invalidates its INVALID_PROPERTIES flag

* fixed transfer function shader
* let processor unlock call after execution be handled by seperate thread

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...
