kanso/dashboard — Issue #2: Need to make sure app_url is preserved on /install page if login needed

From an install link request in the garden to a dashboard, we have a url that looks like

```
/install?app_url=http://garden.iriscouch.com/garden/_design/garden/_rewrite/details/wiki
```

When dashboard shows the page, and the user is not logged in, there needs to be a way to login and go back to the same url with the app_url preserved.
