This PR updates the window controls overlay code to remove the
dependency on `sharp`, which is a natively-compiled Node library that is
really hard to package for Electron given the way that we strip node
modules after bundling. I've replaced this with `pngjs`, which has a
smaller footprint and is still relatively fast (it doesn't need to be
perfect since it runs on the Node process instead of the browser
process).
Adds a new set of configurations for managing whether the app will
automatically check for updates. Ports over the auto update code from
the old app. In this version, the main difference is that updates can be
manually checked for using a menu bar item, even if auto updates are
disabled.
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.
