Error Handling

[BenjamenMeyer]

We need to have proper error handling throughout the stack so errors can be detected and handled. One example is when we fail to load a game (#149); the user should be sent back to the load game screen - at present there's not much we can do to provide that kind of experience.

This will require work to be able to shunt errors between Python and C++; as well as handling throughout both Python and C++.

Considerations:

• C/C++ side can use error code returns or exceptions
• Python should use PyExceptions (https://docs.python.org/3/c-api/exceptions.html)

While I personally don't care for Exceptions; given our integration with Python it's probably best to standard on Exceptions in both. This would also mean moving much of our C methods over to being more C++ oriented.

This would also enable more capabilities with finding issues.

This is the theme for the first major refactor that will lead to 0.9.x.
