Cross linking should work in navigation

[DanielCaspers]

Clicking a button (besides the navbar) should bring you from one page to the other. For example, a person from tab-activities should successfully bring you to their page. Intro to AngularJS should help with this. We can't simply use hyperlinks - we need to track state in some way.
