Modify API of signup to accept only correct emails.

[Raesquiv13]

As the product owner, I want to:

When a new user is going to be created, verify that the email has the correct format: The email must have an @and after the @must have a . for example:

• user@hostapp.com

If the email doesn't have the correct format API will respond status : 400 message : Error, formato de correo incorrecto

To validate if the email has the correct format, i am going to use a regex. Email regex: /^[-\w.%+]{1,64}@(?:[A-Z0-9-]{1,63}\.){1,125}[A-Z]{2,63}$/i

The regex was found here: https://es.stackoverflow.com/questions/142/validar-un-email-en-javascript-que-acepte-todos-los-caracteres-latinos
