modifications generated via the script FindRedundantHeaderIncludes.py

 All this stuff have been moved into Monteverdi
 To achieve this goal, I removed:
 - Utilities/FLTK
 - Code/Gui
 - Code/Visu (old visualization framework)
 - Code/Visualization
 - and their relative tests and examples
Some modifications have been also done into some CMakelists.txt to remove all links to visualization

Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

NOTE: MUST USE GNU compliant version of sed
Run the following shell code (Adopted from Brad King scripts for CMake):

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed \
&& git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' \
   | xargs sed -i -f convert.sed \
&& rm convert.sed
