Picky me says let's add all of these as app.locals since the login server will now have more than one page.

So...

```javascript
app.locals({
  hostname: env.get("HOSTNAME"),
  audience: env.get( "AUDIENCE" ),
  ga_account: env.get( "GA_ACCOUNT" ),
  ga_domain: env.get( "GA_DOMAIN" )
});
```

If you want to do ```res.locals``` for email and csrf that would be cool!
