* Keep the user on login page on failure
* Show an error if username already exists
* Check the password format in the backend
* Return a better message if username is invalid
* Add a title to the login page
* wip: Improve look of login and register pages
* Set a capital M in username help message
On the registration page, username tip started with a minuscule, while
the password tip started with a capital.
* Change message if username is taken
This feature is optional. It is based on the presence of a
`data/tos.html` file that an administrator can create. If this file
exists, FreshRSS will automatically add a "ToS" checkbox on the
registration page that users must check to be able to create their
account.
* 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.
