Support superpowers:// links to join a server or project

[elisee]

That would make it very easy to join a server or project through the app.

From Gitter:

We could use Electron to register a custom protocol: https://github.com/atom/electron/blob/master/docs/api/protocol.md
and then links like superpowers://1.2.3.4:4237/ could work?
with a redirect service so that it links in most chats: something like http://server.superpowers-html5.com/#1.2.3.4/4237 that redirect to superpowers://1.2.3.4:4237/

And if the superpowers:// doesn't open the app, the page could still offer to connect directly through the browser. Best of both worlds!

OK so turns out electron.protocol is just for handling links within the app, not from the browser.

The alternative seems to be https://github.com/jden/register-protocol-handler which only works on Windows currently (https://github.com/jden/register-protocol-handler-windows) and uses http://npmjs.com/package/edge to communicate with .NET. Seems like a bit overkill? I don't know.

On GNU/Linux systems, registering a custom protocol works through xdg-open. It's a matter of creating a desktop file when installing Superpowers.
