configuration files saved without formatting values

[afdaniele]

The configuration file for the core package (and I guess the others packages too) are dumped with the values not formatted according to the metadata of the configuration.

For instance, the file metadata.json of the configuration for the core package reads:

{
    "configuration_content" : {
        "maintenance_mode" : {
            "title" : "Mainteinance mode (NOT YET IMPLEMENTED)",
            "type" : "boolean",
            "default" : false,
            "details" : "Whether the platform is in maintenance mode"
        },
        . . .
    }
}

whereas after pushing a new configuration from the browser, this is what the file configuration.json looks like:

{
	"maintenance_mode": "1",
	"navbar_title": "Welcome",
	"logo_white": "http:\/\/compose.afdaniele.com\/images\/compose-white-logo.svg",
	"logo_black": "http:\/\/compose.afdaniele.com\/images\/compose-black-logo.svg",
	"admin_contact_email_address": "administrator@example.com",
	"cache_enabled": "0",
	"guest_default_page": "login",
	"user_default_page": "profile",
	"supervisor_default_page": "profile",
	"administrator_default_page": "profile"
}

It is clear that maintenance_mode should be formatted to be true rather than 1.
