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

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.

 * added update_legal_header.py script for updating the legal header in all code files of the project
 * ran the file => all TUMVis source files now contain the legal header

 + added PropertyWidgetFactory
 + added AbstractPropertyWidget and StringPropertyWidget
 * replaced own observer implementation of AbstractPipeline and AbstractProperty with sigslot
 * changed PropertyCollection (aggregation) to HasPropertyCollection (inheritance)

 * fixed memory leak in ImageDataConverter
 * added usage of Shader::IgnoreUniformLocationError where reasonable
 * fixed shaders

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
