Fix file line ends

[fingolfin]

These files are in the repository with Windows line ends. They
should be using Unix line ends. To accommodate people using the
repository from Windows, add a .gitattributes file which ensures
line ends are automatically adjusted upon checkout.

[olexandr-konovalov]

Thanks - do you think this is better than following https://swcarpentry.github.io/git-novice/02-setup.html and setting

git config --global core.autocrlf true

globally on a Windows machine, what I usually recommend instead of setting this up in the repository?
