Create a user for the primary developer upon DB init

[rsyring]

Could do this in Keg Auth, but since the app is likely to customize the user, maybe we should do it in the app instead?

Can tie into Keg's db_init_post signal or, as long as DatabaseManager is being customized in app.py can just do:

    def db_init(self):
        super().db_init()
        # If all the developer variables are set, then create our first user.
        try:
            ents.User.add(
                name=self.app.config['DEVELOPER_NAME'],
                email=self.app.config['DEVELOPER_EMAIL'],
                password=self.app.config['DEVELOPER_PASSWORD'],
                is_verified=True,
            )
        except KeyError:
            pass

Definitely in the app.
