Proposa noves funcionalitats

@Laura_B we need more information on what you propose. There are important improvements on both registration and verification procedures. But your proposal is difficult to evaluate. First, registration is different from verification. You can simplify registration but it is almost inevitable to demand: user, password and email address, it is otherwise impossible to avoid double users, or bot-attacks, etc. Verification is different. You can allow participation to participants that are simply registered, not verified. Verification can be of different types, but for a City you need to make sure they have the right to exercise democratic will on that city, you don't want people from outside deciding about your city.

SMS-based verification is almost done (thanks @paarals for pointing it out!) but it needs specific integration with the company that will send the SMS, payment, etc. It is not trivial to have it on your Decidim.

Per la part del registre, si no és té accés al correu electrònic (en aquell moment), un usuari pot registrar-se i iniciar la sessió amb Google, Twitter o Facebook, sense haver de confirmar el compte (ja que ja ho han fet prèviament a la XS) això sí, a l'instància Decidim corresponent s'ha d'haver activat i configurat.
