Changing ace.pyx to play nicely with python3

pyne.ace was complaining about all sorts of things with python3 and I went through and fixed them.
Additionally, some super().__init__() calls weren't being called (correctly or at all), causing errors, so I changed those too.
Honestly, these new functions shouldn't even be in this PR, they're for a totally different purpose. I'm just gonna take em out of this branch.
