Allow custom call back function with multi parameter

[chaosthunder]

Hi Rick Harrison,

Thanks for your validate.js library. It helped us a lot.

And here is my issue: I need to check multi fields for each other:

Ex: min & max fields. check_minmax(min, max) { return (min < max); }

But your callback register only allows 1 parameter.

I want to be able to call back like

validator.registerCallback('check_minmax', function(value1, value2) { return (value1 < value2); });

Can you extend the validate.js so that someone has a way to register multi fields check.

Thank you!
