NEW prepare C+11 (but do not force)

Signed-off-by: Emmanuel Promayon <Emmanuel.Promayon@imag.fr>

WARNING A lot of deprecated functions => lots of compilation warnings.

FIXED Bug 19

NOTE Delete approximatively 300 lines per macro.

NOTE Compilation requires user compiled ITK version 4.x and GDMC 2.6.3 (from Nicolas' sources). Actual GDCM source code on sourceforge does not compile with VTK6 (even if it says so).
NOTE Known errors at runtime : DICOM not openable (directory is seen as a component extension ...). Bug on Windows and Linux : Volumic image are not visible (but present in memory). Should comes from a broken VTK pipeline.

UPDATED CMake policy to CMake version 3.0

UPDATED Improved CMake configuration for including Qt in CamiTK libraries. Work done for library-qtpropertybrowser.

Configure OK (should be missing stuff for compilation and linking).

NEW CMake macro get_git_info to find useful information to configure camitk

FIXED Consequently PhysicalModel::getComponentByName(..) also works with the atoms SC name 
FIXED relax disciplin on PML structural naming
FIXED various comments cleanup (no code change) and of an unwanted std::cout in InteractiveViewer
