Fixed exception on route group

Fixed #12

Basically, if you used in on a group of routes, and these included a GET request, that route would return an exception.

Laravel 6 compatibility

• Added Laravel 6 compatibility.
• Added some PHPDocs to some classes, mainly Exceptions.
• Minor fix to the Transparent Recaptcha (uses the already resolved reCaptcha service instead of resolving it again).
• Updated Travis CI build without PHP 7.1

Fixes helpers

Fixes

• Helpers app('recaptcha') and recaptcha() fixed due to not aliasing the (same) ReCaptcha instance. #6

Multiple features

• Added helper macros to the Request class.
• All Exceptions implements the CaptchavelException.
• Captchavel no longer throws an Exception when the threshold is below (why would you want that!?).

Fixed variable token string (again)

Seems reCAPTCHA is very lenient on the token length. I've seen from 40 char to 360 char. Instead of validating the length of the token, the validation only checks if the token is a string. Whatever reCAPTCHA decides to use in the future, it should be covered.
