Johannes Schickel 40562798d6 Fix our DECLARE_SINGLETON macro to conform to the C++ specs.
We need to use a namespace Common { } there to make strict C++ compilers
like clang++ and comeau happy. I also added a slight comment about why
that is needed to the macro definition and a note that you need to use
it from the global namespace.
