moved matrixprocessor to base module; removed obsolete positiondata.h and transformdata.h from openigtlink module; fixed include statements;

matrixprocessor now listens for dataAdded signals of the data container. also, documentation of the MatrixProcessor class.

contains processing of IMAGE and TRANSFORM messages

Itk reader

ITK Image reader that supports many more image formats.
Example usage edited into the itkfilterdemo pipeline.

 * supports all file formats that can be read via ITK
 * does not support image series

* SliceExtractor FitToWindow property defaults to true to mimic old behavior per default
* PointPredicateRenderArea renders y axis label

* Now supports optional scaling and offset of image
* Added properties for geometry render style and size
* Fixed some scribbling-related bugs

as discussed

Datastructures

basic datastructures for Matrix and position data

Slicerenderer2d

slice renderer that applies transfer function, clips image and/or inverts axes.
tested only with grayscale input images, but should support color and images as well.

* undo changes to .gitignore (regarding SWIG temporary files)
* moved implementation of PositionData and TransformData from header to source file
