feat(build): webpack 4, babel polyfill for async

[glebec]

Assignee Tasks

• added unit tests (or none needed)
• written relevant docs (or none needed)
• referenced any relevant issues (or none exist)

• Closes Upgrade Webpack #76, closes Enable async-await #74.
• Fresher version of replace all promises with async/await #20, but without actually converting any functions to async.
• Removed livereload plugin. Maybe later we can do better via Enable HMR #78.

Is livereload hindering more than helping? If not, wouldn't it make more sense to leave it in until we actually do replace it?

[glebec]

Should have clarified: livereload is currently incompatible with webpack 4. There’s an issue on the plugin to fix it.

[tmkelly28]

Ah, typical webpack. This looks fine to me then - merge away.

I also think it looks good. And I like that you got rid of the bower bit too

[tmkelly28]

Yeah, good riddance bower.
