git: New workflow for CMake

git clone git://cmake.org/cmake.git CMake
cd CMake
git checkout master
git checkout -b finddcmtk
cp ~/Perso/gdcm/trunk/CMake/FindDCMTK.cmake Modules
git add -- Modules/FindDCMTK.cmake
git commit -m"Cleanup FindDCMTK (using foreach). Fix linking on win32 static libs."
git checkout -b next origin/next
git checkout next
git pull
git merge finddcmtk
git config remote.origin.pushurl git@cmake.org:cmake.git
git push

watchout that commit message should be single-lined:

$ git push -v
