[FEATURE] BungeeCord

If you really want to get fancy, support setting up a BungeeCord server.

This is pretty likely for the node.js webui, as Bungeecord uses YAML, I believe, for configuration. Since YAML is an easy include thanks to NPM, I anticipate bungeecord servers having its own creation workflow in the webui.

Too much change is required to profiles to hope to add it to 0.5.x, however, and since the implementation of profiles in 0.6.x is largely undone (or at least, not going to match the previous one), accommodating this kind of server (and others) will be left squarely in the realm of the new webui.
