Real optim state hidden because not passed in

The test job needs to be modified because the API of optim changed. I wasn't going to leave the misnamed state to stand for 'config' and a new 'config' to be the state.
Or do I have to fix the tests now?

There is some problem with the github build environment. I tested the Lua5.2 version and it tests just fine without errors. I have gcc 4.8, while travis build uses old 4.6, maybe that's the problem. In any case, it is not my checkin but the build just fails now, because the 'LessThan' test gives the wrong gradient.
