create desktop GUI app to run/manage spacebrew server

[quinkennedy]

such as was made for ECS. Best option seems to be an Electron app which runs the server as a backend process and uses pipes/IPC/sockets to communicate between the two.

• Electron was suggested for a Node.js-based app
• AppJS is another Node.js-based option
• Since Clojure is Java-based, any Java cross-platform UI toolkit would work (such as Swing)
• Erlang has poor integrated options (wxerlang), but mostly they recommend writing the GUI in something else and IPC between that and the Erlang backend app. Probably a good choice for any language.

Other recommendations welcome.

stretch goal, include an admin interface.

Have a MVP working here (emphasis on the "M"):

"For reals" version will instead have a start/stop button, a way to set the port/other configs, and probably still the admin as a tab or something.
