Plus42 Equations, Preview Release

[Thomas Okken]

I just uploaded a new Android build. I have confirmed that (a) yesterday's build crashes on my own phone as well when run without a state file, and (b) this one doesn't.

I haven't updated the other ones since they don't seem to crash because of this issue, but they will also get the fix anyway when they are built the next time, since the fix is entirely within the core.
