Check on paste

I've noticed there is no check on pasting code which would be handy.

So I've added this piece of code below the keypress function:

    // On paste we have to validate against the mask as well.        
    $(this).bind('paste', function(e) {
        var part1 = this.value.substring(0,this.selectionStart);
        var part2 = this.value.substring(this.selectionEnd,this.value.length);
        if (!mask.test(part1 + String.fromCharCode(event.charCode) + part2))
            $(this).val('');                

    });
