PROTON-1163: Start to use C++11 override to catch problems with handlers
- Add #define to null out override if c++ earlier than C++11

> Allow examples to use C++11 override

>             Project: Qpid Proton
>          Issue Type: Improvement
>          Components: cpp-binding
>            Reporter: Andrew Stitcher
>            Assignee: Cliff Jansen
> The C++11 override feature is extremely useful for detecting when you have 
> the wrong signature for an overridden member function sued for an interface.
> As we are developing the C++ API which uses inheritance from proton::handler 
> in exactly this way it is extremely helpful to get the compiler to find 
> mistakes in this regard especially as the interface changes.
> So this change introduces override in the appropriate useful places in a way 
> that is backward compatible with C++03 and earlier with some small 
> limitiations (essentially you can't use the keyword "override" in your code).
