Add GCC/clang-specific CMake options: ASAN, UBSAN, FORCE_COLORED_OUTPUT

Browse source 
-DASAN=ON   enables the Address Sanitizer (ASan), if supported
-DUBSAN=ON  same for Undefined Behavior Sanitizer (UBSan)
-DFORCE_COLORED_OUTPUT=ON  forces GCC or Clang to use colors in their
                           messages, useful when building with ninja

All three options default to OFF (though when building with make in a
suitable terminal, GCC and clang automatically use colors)

Also modified the cmake_minimum_required() line to shut up deprecation
warnings (though TBH I have no idea if this really still works with
CMake 2.6)
