Overview

Show nicely (but simple) formatted HTML error pages (or respond with JSON if the appropriate `Accept` header is set)) for the http package.

We use html templates to handle simple but as informative as possible error pages.

To eliminate circular dependency in case of an error, we don't store error pages on swarm. We can't save the error pages as html files on disk, or when deploying compiled binaries they won't be found.

For this reason we resort to save the HTML error pages as strings, which then can be parsed by Go's html/template package
