Add a friendly 404 route/page

[Tratcher]

The web application (starter web) template does not have a friendly 404 experience, you end up with a blank page. There should be a default route/page with a simple message similar to the Error page.

@sayedihashimi can you take a look at this?

@DamianEdwards any thoughts about what default content we want for a 404 page? If not I can work on a proposal and send it your way.
