v1.1.2 — Fix silent stat corruption from mouse scroll

Critical bug fix: NumericUpDown's default mouse-wheel behavior was
hijacking the scroll wheel and silently mutating gil, steps, and
character stats whenever the cursor happened to be hovering over a
numeric field while scrolling. Anyone who scrolled past the Stats
tab between opening a save and clicking Save would have their values
changed.
If you got "save data is corrupted" or unexpected stat values from
v1.1.0 or v1.1.1, this is almost certainly the cause. Recommend
anyone on the previous releases upgrade.
