The browser is the new GUI !



Task

Serve our standard text   Goodbye, World!   to   http://localhost:8080/   so that it can be viewed with a web browser.

The provided solution must start or implement a server that accepts multiple client connections and serves text as requested.

Note that starting a web browser or opening a new window with this URL
is not part of the task.

Additionally, it is permissible to serve the provided page as a plain text file (there is no requirement to serve properly formatted HTML here).

The browser will generally do the right thing with simple text like this.
