[Users] Confirm registration as a newly registered user

[netsensei]

As a newly registered user, I receive a nice e-mail with a one-time login link that allows me to active my profile.

Detailed description

As a newly registered user, I receive an e-mail with a one time login link. When I click on the link, I'm automatically logged in (session initiates) without a password. I'm automatically redirected to the "edit account page" and asked to set a new, strong password.

After saving my user account with a valid password, my account is enabled. (default for newly registered users: disabled)

The contents of the e-mail is set in a view in app/Resources.

Possible implementation

See: https://symfony.com/doc/master/bundles/FOSUserBundle/emails.html

• When I register as a new user, I'm redirected back to the dashboard page. A flash message will notify me that a one time login link was send to my e-mail
• When I click as a newly registered user on the link, I'm redirected to the edit page / form of my user profile.
• When I first set and save a valid password / my account, my account is "enabled" and a flash message is shown saying "You're account is now fully activated."
• The one time login is only valid for a limited number of hours / days, after which it expires.
• The request new password link on the login box / page, actually just resends the e-mail with a one-time login to reset the password.

This was implemented. But a few things are left to be done before we can close this:

• Model the confirmation e-mail properly.
• Redirect the user to the "edit profile" page with the explicit request to set the password.
• Implement disabled / enabled status of an account based on confirmation.

The last bullet of the previous comment has been implemented. Still two todo's left on this one.
