This release bumps the version number up to `4.0.0` as it contains major
changes to how Neofetch is packaged and installed.

The entirety of Neofetch is now contained within a single executable.
Everything has been in-lined. Installing Neofetch is now as easy as
downloading the script and running it.

Packaging Neofetch is now easier as well. We were using `sed` in the
`Makefile` to replace specific paths and we have had to work around
different system hierarchies. None of this is necessary anymore.

Those using distributions with an outdated Neofetch version in their repos
can now easily install the latest version.
