Change line endings from carriage returns to line feeds

[rensbaardman]

Some files still had Windows-still carriage return (\r\n) line endings. Messes up git tools.

Wanted to do this in a seperate commit / PR, as to cause as little 'git blame'-noise as possible.

@rensbaardman you should add a .gitattributes file and enforce LF so that this does not happen again.

# Enforce Unix newlines
* text=auto eol=lf
