Implemented reading of whole directory structure and post-processing of tissue classification into a single multi-channel image into IvusTcDemo pipeline.

* Introducing IvusBatchReader processor to read an IVUS volume from a batch of 2D images
* Introducing IvusTcDemo pipeline stub

Added directories of various needed resources (textures, sampledata) to the CampvisShaderDirectories CMake variable, which is used for deployment. Replaced various occurences of CAMPVIS_SOURCE_DIR with ShdrMgr.completePath().

Removed ProcessorDecoratorShading and replaced all of its usages with the new LightSourceData API. This also includes adding LightSourceProviders to the corresponding pipelines.

refs #547

* Introducing SliceExtractor::onEvent() to handle mouse events and generate point scribbles from it, which are then published using the s_scribblePainted signal
* Implemented SliceExtractor being able to render geometry in the slice space (with correct clipping)
* Implemented creating and handling of scribbles in VolumeExplorer in cooperation with the SliceExtractor. Therefore, mouse events are passed to the SliceExtractor, the VolumeExplorer takes care of assembling the scribbles into proper geometry, which is finally rendered by the SliceExtractor. The scribbling can be optionally turned on using the VolumeExplorer::p_enableSclibbling property.

Beautifying VolumeExplorerDemo and VolumeRendererDemo sample rederings by fine tuning transfer functions.

* fixed VolumeExplorer/VolumeRenderer not correctly updating the proxy geometry due to missing locks and thus skipped invalidations
* adjusted VolumeExplorerDemo image URL

Loading can be done with genericImageReader, however, assertion fails for sliders. thread ownership issues

Added smallHeart.mhd sample volume to repository, all demo pipelines in vis module refer to this file. Hence, all vis pipelines should work out of the box from now.

* Moving to Apache 2.0 license
* Updated AUTHORS.txt

Work on Issue #44: Removed GLContext interface and merged functionality into GlCanvas. Introducing abstract (Qt-free) tgt::GlContextManager interface, being implemented by tgt::QtContextManager. Further clean up of related code.

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)

Instead of having the LQ mode tied to the pipeline, each VisualizationProcessor has now a lqMode property effectively halfsampling the viewport size. The TrackballNavigationEventHandler was adapted to these changes and thus simplified.

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

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

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