[PATCH] KDoubleSpinBox and KDoubleValidator

Hi!

Since I've stumbled now for the n'th time over the fact that there's no 
spin box for fractional numbers and KDoubleNumInput hasn't got a 
spinbox, either, I sat down and wrote one. In the course of that I 
found KFloatValidator lacking precision support and implemented 
KDoubleValidator, which cleanly inherits from QDoubleValidator more or 
less just adds localization support. The KDoubleValidator::validate() 
method could've been made more intelligent, but then I'd have to 
cut'n'paste much code from KLocale::readNumber(). Let's wait instead 
that either QDoubleValidator's decimalSymbol() etc become config'able 
in Qt4 (so KDoubleValidator could become a trivial subclass) or that 
someone extends KLocale::readNum() to report QValidator::State-like - 
well, state.

KDoubleSpinBox could use a bias for when
  ( maxValue() - minValue ) * 10^precision < INT_MAX - INT_MIN
but
  max( abs( maxValue() ), abs( minValue() ) ) * 10^precison > INT_MAX
but that can be implemented when it turns out to be needed.

Please consider adding to knum{input,validator}.{h,cpp}

KFloatValidator should be marked obsolete, since it can't do precision 
validation and doesn't understand anything but decimalSymbol() anyway.
