v0.31 stability + collecting error logs

There are no content or gameplay updates this time. There are some small bug fixes around battle result calculations, but the main part of this update is error handling.

As a developer, I'm usually happy with how the game works and how stable it is. The experience might be different for other players, however. Different system versions, different software, different hardware, any kind of computer difference (or even a different playstyle sometimes) might cause problems and I did not even know about them. Here comes version 0.31. If the game happens to crash, it collects information about the possible cause of the glitch and, with player's permission, sends it to me. I really hope this would help me to improve the game code's quality by eliminating some more nasty bugs and annoying glitches.

Have fun and enjoy the game!
