Add DISABLE_CLASS_COPY macro (and use it)
Use this macro to disallow copying of an object using the assignment operator or copy constructor. This catches otherwise silent-but-deadly mistakes such as "ServerMap map = env->getMap();" at compile time. If so desired, it is still possible to copy a class, but it now requires an explicit call to memcpy or std::copy.
