Cannot create new users

[igorsantos07]

First of all: I'm amazed to see we now have a web interface!!!!

So, I'm trying to use Rainy 0.5.0 since suddenly 0.2.3 stopped working for me. I just downloaded the zipball.
However, I noticed the users are not created in the settings file anymore. Using the web interface, however, I can't add new users either. Here's the log with the request:

And my settings.conf:

    DataPath: "/var/tomboy/",
    Backend: "filesystem",
    Postgre: {
        Username: "rainy",
        Password: "rainy",

    },
    AdminPassword: "tomboyadmin",
    AllowSignup: false,
    RequireModeration: true,
    Development: false
}

The filesystem bacend is deprecated and will be removed in future versions. For Rainy >= 0.5.0 you could use the sqlite backend, which will still work with a single file and does not require a network database.
