The VTK utility: Utilities/Maintenance/WhatModulesVTK.py discovers
which modules are used in a project. This patch modifies the Slicer
CMakeLists.txt file to only load the vtk modules used by Slicer. This
should reduce the number of libraries being linked.

This commit also updates CTK project including a patch reducing
the number of library associated with CTKImageProcessingITKCore library.
