Disable timer mocking and enable verbose output.

Fixes #377

* Small grammatical correction

* Fix another grammatical error for consistency

Fixes #119

This allows users to avoid CORS in simple projects that are hosted on the same server as backend.

* Added a reasonable config for autoprefixer (resolves #73)

* Moved autoprefixer config to webpack.config

Should be safe since SO uses it

* Added a note with instructions on eslint plugin configuration

Since the only editor that I found the issue was Atom, I added
just the instruction for the linter-eslint plugin.

* Change the format of the instructions and add screenshot.

The current one is not drop-in anymore

Fixes #186

* Transform async functions with regenerator

Remove `transform-async-to-generator`, which to my understanding is meant
to be used in environments that support generators natively.

Because we're compiling generators to ES5 anyway, we can simply use
`regenerator` to transform async functions too, which results in
slightly simpler output and only uses the regenerator runtime instead
regenerator runtime + _asyncToGenerator Babel helper.

* Add babel-plugin-transform-regenerator

* Use dependencies with an exact version

Fixes #322

* Make Babel config more verbose and simpler

* Support async/await

The problem has since been fixed upstream.
