Igor Okulist and Damien Buhl (Patch #14). Added support for running tests and building with DLL on Windows. - added missing JSON_API - Visual Studio DLL: suppressed warning "C4251: <data member>: <type> needs to have dll-interface to be used by..." via pragma push/pop in json-cpp headers. - New header json/version.h now contains version number macros (JSONCPP_VERSION_MAJOR, JSONCPP_VERSION_MINOR, JSONCPP_VERSION_PATCH and JSONCPP_VERSION_HEXA). While this header is generated by CMake, it is committed to ease build with alternate build system (CMake only update the file when it changes avoid issues with VCS).
