Navbar now collapses properly, fixes (PW-2)

Turns out it was being caused by a disabled less file. Easy fix.
Changed links in navbar and disabled active class

Since we're now using templates, we can't use the class="active"
directly.

Two possible fixes that come to mind, but are far from being perfect:

1. We could use a js script on every page that sets the active element.
But this is just hacky.

2. We shouldn't use the navbar template, but then this defeats the whole
purpose of having templates.
