Add support for Laravel 6.x email rules

[yangm97]

Opening so I don't forget about this, details to come.

Basically if you have something like this in your FormRequest.php:

            'email' => 'required|email:rfc,dns,filter',  

The generated frontend code from this package doesn't attempt to validate to use other rules (such as dns and filter).

I guess the solution would be to make a request to the back end to validade this, but I just discovered this project today so I could be wrong :D.

Looks like an outdated email rule implementation -

laravel-jsvalidation/resources/assets/js/validations.js

Line 482 in a40ffc2

Email: function(value, element) {

It's only validating the input email against a regex - https://jqueryvalidation.org/email-method/

Support for rfc, dns, filter etc was added in Laravel 6.x

• https://laravel.com/docs/5.5/validation#rule-email
• https://laravel.com/docs/6.x/validation#rule-email

I've marked this as a feature request.

It would be preferable if it could be implemented at JS level. That said, given the reliance on third-party PHP lib and differences in between PHP+JS regex implementations, I'm not sure what's worse, duplicating regexes into JS and having to maintain them (to keep up with the PHP lib), or having to make another AJAX request.

The main motivation is to do with this lib is to do whats possible at JS level, otherwise it would be quite simple to just make all rules fire an AJAX request.

Thanks @bytestream ! I guess it makes sense to do rfc validation on the client side since it's a standard so any differences between implementations should be seen as bugs on either side.

As for the other rules, think it would make sense to do the AJAX requests since they're pretty much PHP lib specific, but it shouldn't be much of concern since the default email rule is rfc, so, by default, this lib wouldn't make those AJAX requests.

Hey @yangm97 you could try #505 on the dev-form-requests branch. I've converted it to a single AJAX requests so all validation is handled by Laravel. It seems OK from some usage in my app but needs some more testing.
