While i enjoy the netlingo with smileys and emoticons, we need to be putting out a more helpful 404 page to the world that explains what's happening.

@jcarpenter, ux thoughts?

## Environment :
* Otoro daily: 9-25-2012
* gaia commit: 71e89d4338d59a86e8599abeda24dbfaf1c80e1a
* gecko commit: 1c333645ec70bfce2176876e4bfaf24bfd4bbde5


## Repro :
1. launch Browser App
2. Load a page that will throw a 404
3. Verify the error page fires a sadFace image with buttons.  But there's no real helpful text to the user on what happened.

## Expected :
* Have a more professional page that describes what err'd out to the user on this page.  :( face doesn't explain anything.

## Actual :
* sadFace page

Weren't we supposed to show the default error message that Gecko displays?

We are supposed to be showing error messages from gecko for non fatal errors, I think your page actually crashed while it was loading

What is the specific url? and can you test another url that you expect to 404 (probably from a different domain)

Styling for the crashed page is files under #4045

What is this bug actually about? We show network errors from Gecko and the crash screen for fatal errors as per spec.

Please re-open if there's any work left to do on this.
