As a principle, static libs should not dllexport methods; that should only be used when building DLLs.

Case in point: when static libs with dllexport directives are linked into DLLs created with a .def file, the VC++ compiler exports the dllexported methods into the DLL, in addition to the exports listed in the .def file. This will result in undesired link dependencies and is not the correct thing to do.

I've also cleaned up the vcxproj a bit by consolidating duplication.
