This removes the Vagrantfile and updates the documentation to remove
the steps which explain how to install Docker in a VM via Vagrant.

1. All titles are listed by simple platform names apart from Windows' "Installing Docker On Windows". Changed this to "Windows" to match the rest.
2. Some articles' description (and title) information does not match the majority. Modified them to match the rest (i.e. Please note this project is currently under heavy development. It should not be used in production.)
3. Removed "Linux" from Gentoo & Ubuntu descriptions.
Added further information regarding how to access BIOS menus on Windows machines (laptops). My laptop required restarting to find the options and this information will undoubtedly help other users.
