[html-formfu] Deflator/Inflator::FormatNumber

[onken at houseofdesign.de]

Hi Carl (and everyone else :-) ),

I wrote a deflator/inflator couple for Number::Format.
The locale can be specified as well as precision and trailing zeroes.

I'd be glad if you would have a look at it and consider to add it to
FormFu. The only disadvantage is that Number::Format fails on some systems.
But I already contacted the author and send him a patch for the failing
tests.

cheers,
