card validate

I filled all info, and expire date with 33/12.
card.isValid() return true.
it should return false.

The function starting on line 1201 of skeuocard.js (ExpirationInputView.prototype._onKeyUp) takes the number you input and returns a date object. For some reason, if you use a month > 12 it will return a valid but incorrect date object. I made a workaround for this.

It was returning the date as long as month and year are not equal to zero. It was doing this by these lines:
dateObj = new Date(year, month - 1, day);
this.date = dateObj;

I changed it to return a date in the past if the month is > 12 like this:
if (month <=12) {
dateObj = new Date(year, month - 1, day);
} else {
dateObj = new Date(1900,1,1);
}
this.date = dateObj;

Since 1900 is in the past, Skeuocard recognized it as an invalid date.
