Web interface doesn't load properly after changing to aardvark

I compiled the latest devel and did:
```
sudo service arangodb stop
sudo service arangodb upgrade
sudo service arangodb start
```

After loading up the web ui in the browser, I get a blank page with a background color.

In firebug, some resources were not loaded:

```
"NetworkError: 404 Not Found - http://localhost:8529/_admin/aardvark/img/footer_hd_bg.png"
"NetworkError: 404 Not Found - http://localhost:8529/_admin/aardvark/img/bg_paper.gif"

app.js (line 8434)
GET http://localhost:8529/_admin/aardvark/js/templates/aboutView.ejs 404 Not Found

app.js (line 66646)
uncaught exception: There is no template at js/templates/aboutView.ejs
```
