Fix HUD bug with specified decimals

If any stat in HUD had manually specified number of decimal places, the
entire hand processing stopped when the first such stat was encountered.

Now really do the decimal place formatting as it was supposed to work.
Also, for future reference: tuples are immutable - you can't overwrite
any tuple member. Hence the need for new routine, __stat_override()
