Adds electron-builder, which we will use to package and distribute our
application, same as in the existing app.
Replaces explicit port assignments with dynamic ones, which are then
stored into environment variables.
Adds a ~/.w2-dev folder for use when running a dev build.
The build-helper pipeline from the old repo is included here too, but it
is not updated yet so it will fail.
Also removes some redundant utility functions and cleans up some let vs.
const usage.
The packaging can be run using the `package:prod` and `package:dev`
tasks.

Fixes the New Window menu item so that it shows the new window after it
loads and captures any errors that occur. Also adds a keyboard shortcut
for new window and uses the native shortcut for close window.
