* refactor: bundle the browser and renderer process electron code * Bundles browser/init and renderer/init * Improves load performance of main process by ~40% * Improves load performance of renderer process by ~30% * Prevents users from importing our "requiring" our internal logic such as ipc-main-internal. This makes those message buses safer as they are less accessible, there is still some more work to be done though to lock down those buses completely. * The electron.asar file now only contains 2 files, as a future improvement maybe we can use atom_natives to ship these two files embedded in the binary * This also removes our dependency on browserify which had some strange edge cases that caused us to have to hack around require-order and stopped us using certain ES6/7 features we should have been able to use (async / await in some files in the sandboxed renderer init script) TLDR: Things are faster and better :) * fix: I really do not want to talk about it * chore: add performance improvements from debugging * fix: resolve the provided path so webpack thinks it is absolute * chore: fixup per PR review * fix: use webpacks ProvidePlugin to keep global, process and Buffer alive after deletion from global scope for use in internal code * fix: bundle worker/init as well to make node-in-workers work * chore: update wording as per feedback * chore: make the timers hack work when yarn is not used
