Use email instead of username

[winzou]

As stated in #88

[pjedrzejewski]

Nice, for sure you also have to update the scenarios. :)

[stloyd]

TBH. I would prefer to give a choice for developer which type of authentication he wants:

• username,
• email,
• username or email

[winzou]

@stloyd could be interesting but how do you do that?

[jjanvier]

simply by configuring this https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/doc/logging_by_username_or_email.md :)

a key in parameters.yml could do the trick

[winzou]

OK but you still have to make different registration/login forms for each cases.
I don't think we can offer that out of the box, or even if it worths it. But this is really easy for developers to implement it:

• With this PR they got an email authentication out of the box;
• By simply deleting the fos_user config key of this PR they can switch back to username;
• If they want both (username and email), they can change the FOSUB provider as @jjanvier pointed out.

@pjedrzejewski I've updated scenarios.

[pjedrzejewski]

Requires rebase against latest master. :)

[winzou]

Waw, I don't really know what I've just done with the rebase. It seems OK but github shows all the merged commits again, I don't know if it's a good thing.

@pjedrzejewski can you still merge that or not?

[pjedrzejewski]

@winzou Can you pick only the right commits and fix this branch or reopen this PR? If no, I'll try to fix it! :)

[winzou]

I should be able to do that tonight I'll let you know.
