gnc_numeric: fractional displays and rounding

You may have noticed that I have committed the new decimal conversion
function to gnc_numeric.c (r17421) and made a few fixes based on it.
However, I noticed that sometimes fractions print with weird rounding. For
example, if the print_info settings specify rounding and force_fit, the
fraction "1/3" could print as "0 + 200003/600000". It seems that rounding is
applied to non-decimal numbers but force_fit is not. This doesn't make sense
to me. Why would you do decimal rounding on something you intend to print as
On the other hand, if force_fit is supposed to make any value print in
decimal form, then the following patch does that.
What do you think?
