 * started converting old multi-threaded OpenGL code to new job-concept
 * painter and evaluator of a VisualizationPipeline now share the same OpenGL context

 * introducing OpenGLJobProcessor (the name somehow sucks...)
 * renamed JobPool to PriorityPool (still needs some work)
 * AbstractPipeline::executeProcessor() now takes a pointer as argument (necessary for job pattern)

 * 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

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...
