FloatValidator

[Alin Eugen Deac]

We need a float validator - yet, I had some trouble to figure our how to specify PHP's max float... Could use INF again... but not sure how this will work.

Also - Another option needs to be added to this (apart from range) - decimals; how many decimals do you wish to allow... Handy for instance when a custom price validator will be created
