Altered the message alert class and positioned it absolute to
 the body to have floating messages.

The styling of the homepage is back to the styling of the `master`
 branch, but responsive. Needs detailed styling edits for i.e.
 the mobile menu.

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