Cannot set stepping via w

[Daniel-Beardsmore]

You can't achieve stepping by setting a keycap to its desired width, then reducing w to be less than w2. This does not even work when Stepped is checked.

I agree that this could be confusing. I've made a tweak to the algorithm for v0.9... now I generally won't force-sync width & width2 if "stepped" is checked. ea0ebdd
