Support building as a shared library

On Windows, it is necessary to add some __declspec() calls to expose
some symbols with different linkage types. This commit adds the makes
it possible for users to easily build cucumber-cpp either as a static
or dynamic library by defining either CUKE_LINKED_AS_SHARED_LIBRARY or
CUKE_CREATE_SHARED_LIBRARY at build time.
