h8'ing things fails with ugly trace if you're not logged in.

I wanted to report this for hip2.it, but I see no source for that, and since I guess it's 99% the same source as this, and the issue happens with ih8.it too...

The issue:

If you point someone to a link like https://ih8.it/h8?url=http%3A%2F%2Fexample.com (from, say, a blog's custom 'share' button), and they're not logged in (probably never used the service before), the result is an ugly trace, like:

Express
500 Error: User is required
at userRequired (/opt/ih8.it/app.js:282:22)
at callbacks (/opt/ih8.it/node_modules/express/lib/router/index.js:272:11)
at userAuth (/opt/ih8.it/app.js:272:17)

The expected behaviour would be redirecting the user to the login page.

Cheers!
