Alpha 0.1.2 Update

I got a fair number of bug reports about issues scattered about that I had missed. I'm hoping this fixes most of them. This should especially fix Linux support, which previously did not work at all and I'm sorry about that. Should be fixed now.

In addition to fixing Linux compatibility, the Tab system has been reworked to be more stable and consistent, as well as persisting progress across restarts of the client. Let me know if you have any issues with it, and the persistence can be toggled in settings.
