Switched project label to use 'nicer' suffix (e.g., md instead of /MD)

It seems that it's not necessary to export those members (as long as you can't access them), and most of them are STL instances, which apparently cause lots of problems for DLLs. (For example, you simply can't export instances of std::map; see http://support.microsoft.com/kb/168958.)
