Improvements on tests

[dorianneto]

This PR contains:

• Tests to the "containsCaseless" method from class Str
• Builder class to help the tests
• Some comments in validator file methods

I forgot to describe the methods on comments. I'm sorry for this :/

[dorianneto]

Fails when runs on php 5.6

{
  "language": "php",
  "php": "5.6",
  "install": [
    "composer self-update",
    "composer install"
  ],
  "group": "stable",
  "dist": "trusty",
  "os": "linux"
}

I would like to support Laravel >= 5.2, it requires at least php >= 5.6, but if your feature it's not compatible maybe we need to remove that php 5.6 support and only point to laravel >= 5.5. Obviously re-tagging this package.

@arandilopez It will not be necessary because was a stupid error commited by me :P

In the Builder class, specifically on validate method, I setted the same method parameter name for the list() method variable. I'm sorry for this :/

Let's continuos make support to Laravel >= 5.2 because there are many projects that use yet.

@dorianneto I'm gonna merge it

I love that Builder.

❤️ thanks
