Auto-Reload debug using electronmon

[Atomic-Germ]

Context / Background

While I was doing some front-end experiments, I realized it would be nice if it would just reload itself whenever I save a file. This is my solution to that.

What change is being introduced by this PR?

• How did you approach this problem?
  I basically just looked at what others before me have done.

• What changes did you make to achieve the goal?
  Install one devDependency, and alter a script in package.json

• What are the indirect and direct consequences of the change?
  When editing files, the app will reload when a front-end file is changed.

How will this be tested?

• How will you verify whether your changes worked as expected once merged?
  Running a debug session and noting that it reloads after a small change to a css or other file.

Switching to electronmon for much better performance

Interesting, we used to have something in place, which was electron-reloader, but we recently broke it and had #1137 tracking it.

Do you know how one compares to the other, in terms of pros/cons?

Well, it reloads a little ungracefully if you’re trying to use the electron dev tools while debugging. BUT, it’s a lot faster, and it’s a lot better than restarting it yourself.
