More user-friendly desktop application

Right now, the preferred way to run the editor is by deploying it to some servlet container. This is quite easy (especially with the "Deploy to Heroku" button).

But running the editor on localhost currently involves running a platform-specific startup script (variED.sh) and then opening the web browser manually on the right page.

Although it is considered cancer by some, Electron might be just the right thing here. We could also try integrating it into Eclipse (it actually works with Eclipse's internal web browser), although this is not the best user experience, with the editor-in-editor approach.
