Instead of returning a raw pointer from CZMQNotifierFactory and implicitly requiring the caller to know that it has to take ownership, return a std::unique_ptr to make this explicit. This also changes the typedef for CZMQNotifierFactory to use the new C++11 using syntax, which makes it (a little) less cryptic.
