Last commit was incomplete as the
 gitignore was not suffiently working on
 all static files.
It now includes the renewed template files
 to make the homepage reponsive. Also, it
 completes the configuration for Bootstrap
 Webpack loader.

Update and configure to Webpack@2.x
 and install Bootstrap@4.0.0@beta-6
 loader. Configured to start using
 .scss files.

The `static` folder will be ignored in the future commits. All
 existing files in this folder in the repository are now removed.

The README.md file is updated to include a correct workflow
 on how to deal with static files.

Added a NPM packages.json list which manages
 JavaScript packages. Most important packages added
 is the Webpack package which acts as an assets
 bundler.
It is added in its most basic working form. This
 includes additional settings in `settings.py`
 and the template tags in `base.html`.
Please read the updated Readme.md to easily get
 started using Webpack for your new assets.
