Keep unminified JS files in builds

[vitkarpov]

Fixes #149

This is a breaking change! (for 3.x release)

👆 that's how build folder looks like after running npm run-script build. What's been likely before turns into likely.min now and likely file is unminified instead.

How does it work

Minification feature is built-in and runs under -p flag. There are 2 configs now: base is what we already have and webpack.config.min.js inherits the base one. The min config has "min-postfixed keys" in entries to get [name].min.js files.

npm run-script build runs Webpack twice: one without -p mode with the base config and another in production mode (that's where minifications come) with the min config (to get proper file names).

@NikolayRys I'm not sure why tests fail 🤔 Is it something CI specific? I didn't notice that locally, will take a closer look then.

Hi, thank you for the pull request, we need it for 3.0.

I'm a bit busy right now, but I'll review this one and other PRs next week.

@vitkarpov, awesome job, thank you!

• Please merge/rebase from master: it'll fix the Travis build.
• Change commit messages to follow GitHub commit style: https://gist.github.com/robertpainsi/b632364184e70900af4ab688decf6f53
  Essentially you just need to remove feat/chore in the beginning and capitalize the rest.
• Add the new build files to git repo.

@NikolayRys done 👌

@NikolayRys I reviewed this PR one again and noticed a thing I'm not sure about and one thing that probably needs to be fixed:

• there are 2 files: likely.js & likely-common.js but actually they are the same since it's Webpack universal module definition, so a single file works both in the browser and node.js, what do you think? (please, look at built files)
• likely.css becomes unminified. Do we need likely.min.css or leave likely.css minified?

Nah, I see the difference now:

window.addEventListener('load', () => {
    likely.initiate();
});

Everything's fine then.

Oh, it's a very good point about css. I think, we need to be consistent now and have likely.min.css minified as well, could you please add it too?

Also, please remove the 3.0.0 bump, we are not there yet to finalize the release, and there will be several more changes to it, here's the list: #163
It's okay if this change brakes it because it happens only in the master, which is not meant to be stable.

Yes, will do within this PR.

Also, please remove the 3.0.0 bump, we are not there yet to finalize the release

Gotcha, do we need to add built files to the repo then? Anyway, it shouldn't hurt anybody.

@NikolayRys Done 🎉

Thanks for the good work, this was a useful change.

About the builds, we were keeping them always in this project in the repo, it's just for consistency and for the case if somebody wants the edge version :)
