Provide email address verification feature (#2481)

* Add an email field to the profile page I reuse the `mail_login` from the configuration. I'm not sure if it's useful today (I would say it was used when Persona login was available). A good improvement would be to rename `mail_login` into `email` so it would be more intuitive to use. * Add boolean to the conf to force email validation This commit only adds a configuration item. * Add email during registration if email must be validated * Set email token to validate when email changes * Block access to FreshRSS if email is not validated * Send email when address is changed * Allow to resend the validation email * Allow the user to change its email while blocked * Document the email validation feature * fixup! Allow the user to change its email while blocked * tec: Autoload PHPMailer lib * Validate email address format * Add feedback on validation email resend action * Allow to logout when user is blocked * fix: Change default email "from" * Reorganize i18n keys * Complete all the locales with default english * Hide sidebar (profile page) if email is not validated * Check email requirements on registration * Allow admin to specify email when creating users * Don't check email format if value is empty * Remove trailing comma in userController Co-Authored-By: Alexandre Alapetite <alexandre@alapetite.fr> * Set PHPMailer validator to html5 before sending email * fixup! Remove trailing comma in userController

+# Configuring the email address validation
+
+FreshRSS can verify that users give a valid email address. It is not configured
+by default so you'll have to follow these few steps to verify email addresses.
+
+It is intended to administrators who host users and want to be sure to be able
+to contact them.
+
+Note that this feature only works with PHP >= 5.5.
+
+## Force email validation
+
+In your `data/config.php` file, you'll find a `force_email_validation` item:
+set it to `true`. An email field now appears on the registration page and
+emails are sent when users change their email.
+
+You can also enable this feature directly in FreshRSS: `Administration` >
+`System configuration` > check `Force email addresses validation`. If the
+option doesn't appear, it means that you use PHP < 5.5.
+
+## Configure the SMTP server
+
+By default, FreshRSS will attempt to send emails with the [`mail`](https://www.php.net/manual/en/function.mail.php)
+function of PHP. It is the simpler solution but it might not work as expected.
+For example, we don't support (yet?) sending emails from inside our official
+Docker images. We recommend to use a proper SMTP server.
+
+To configure a SMTP server, you'll have to modify the `data/config.php` file.
+
+First, change the `mailer` item to `smtp` (instead of the default `mail`).
+
+Then, you should change the `smtp` options like you would do with a regular
+email client. You can find the full list of options in the [`config.default.php` file](/config.default.php).
+If you're not sure to what each item is corresponding, you may find useful [the
+PHPMailer documentation](http://phpmailer.github.io/PHPMailer/classes/PHPMailer.PHPMailer.PHPMailer.html#properties)
+(which is used by FreshRSS under the hood).
+
+## Check your SMTP server is correctly configured
+
+To do so, once you've enabled the `force_email_validation` option, you only
+need to change your email address on the profile page and check that an email
+arrives on the new address.
+
+If it fails, you can change the environment (in `data/config.php` file, change
+`production` to `development`). PHPMailer will become more verbose and you'll
+be able to see what happens in the PHP logs. If something's wrong here, you'll
+probably better served by asking to your favorite search engine than asking us.
+If you think that something's wrong in FreshRSS code, don't hesitate to open a
+ticket though.
+
+Also, make sure the email didn't arrive in your spam.
+
+Once you're done, don't forget to reconfigure your environment to `production`.
+
+## Access the validation URL during development
+
+You might find painful to configure a SMTP server when you're developping and
+`mail` function will not work on your local machine. For the moment, there is
+no easy way to access the validation URL unless forging it. You'll need to
+information:
+
+- the username of the user to validate (you should know it)
+- its validation token, that you'll find in its configuration file:
+
+```console
+$ # For instance, for a user called `alice`
+$ grep email_validation_token data/users/alice/config.php | cut -d \' -f 4 -
+3d75042a4471994a0346e18ae87602f19220a795
+```
+
+Then, the validation URL should be `http://localhost:8080/i/?c=user&a=validateEmail&username=alice&token=3d75042a4471994a0346e18ae87602f19220a795`
+
+Don't forget to adapt this URL with the correct port, username and token.
