* Add signed in check to navigation entries

Enabling routing for getting-started-misc allows the column to be directly accessible, which showed every entry and threw unnecessary errors.

Also fixed the keys as these were literally "i++".

* Remove "Extended information" from getting-started-misc

I couldn't find any reference to this translation string, so I removed it too.
