Add forward declaration header (#422)

* added fkyaml_fwd.hpp to provide forward declarations

* no include of cpp_config_macros.hpp in version_macros.hpp & added define_macros.hpp

* updated amalgamation scripts and CONTRIBUTING.md

* added descriptions about the header file for forward declarations
