[CHANGE] add a pointer to WModule to dataset tree items, this way we can directly access the properties of a dataset in the datasetbrowser

 * #97: expanded WGridRegular3D to allow affine transformed grids (as defined in the NIfTI-format)
 * #141: added cast-constructor to WVector3D to cast from WValue< double >
 * increased required Boost version in CMakeLists.txt to 1.39.0 (for signals2)
 * changed directory of "make cleantest" from binary dir to source dir to allow non standard build dirs

[ADD #13] WLoader has now its own commitDataSet member function which shall be used in the subclasses

[FIX] added path finding code for OSX when not using bundles. We need to add code for bundles later on as shaders will be in a different path (i.e., I guess, in Resources)

[ADD] - added further exceptions
