[1.x] Add option to force the password to have a special character.

[leo95batista]

Hi! I have created this PR with the intention of adding in the password validation rules the option to require that the password contain or not special characters.

Regards.

Looks good to me.

It should probably changed to something like: return __('The :attribute must be at least :length characters and contain at least one uppercase character.', ['length' => $this->length]);

@buismaarten Please check it now. Thanks

@leo95batista looks better!

This PR has merge conflicts. Also why switch(1) instead of switch(true)?

[leo95batista]

Hello, good morning everyone! , @taylorotwell I am reviewing, and I see that the PR #70 was approved first before this PR #65. For that reason the conflict. In PR #70, they changed the style in which the validation message was returned. When creating my PR, I can change the style, but I did not do it to maintain the style that existed initially.

Before

return __('The :attribute must be at least '.$this->length.' characters and contain at least one uppercase character.');

Now

return __('The :attribute must be at least :length characters and contain at least one uppercase character.', ['length' => $this->length]);

I think switch(1) and switch(true) mean the same in that context

@taylorotwell , do you think anything else needs to be changed before doing the merge?
