LGTM on the widget calculator keyboard fix #494.

As far as the #341, it seems the fix is limiting the currency symbol to 1 char? From what I see most of the symbols besides (CHF and XDR) are two 1 or 2 chars. It seems that two chars is displayed just fine on Android, but limiting it to just one feels a bit awkward. Perhaps a bit of a nit, but maybe we could limit to two chars?

Example for PLN (zł) - iOS left:

I changed it so it only truncates to 1 char when the symbol is 3 chars or more. Up to 2 chars it indeed still looks okay.
