Default error page title text is "Matron!"??

Context

The default error page says "Matron!" in large letters. Whaaat?

I think this is an effort to be cute, and that this is supposed to indicate that the hospital matron is being called, or something?

I really (really) don't think this is a good default.

Hi, are you willing to contribute to provide a better default error page?

[lukehutch]

Sure -- there are lots of possibilities (e.g. showing a nice page with a Vert.x logo, or a bare page like the Chrome page showing a little dinosaur logo when a page cannot be reached) -- but even just changing "Matron!" to "An unexpected error occurred" would be sufficient, I think...

Also, to adhere to a "secure by default" mindset, the default error page should not show a stacktrace (although the stacktrace should be shown in the log).
