Fix linefeeds to LF (this mostly matters for Linux/OSX users).

There is _no_ code level modifications just CRLF linefeeds are converted to bare LF.

The .bat files were left to CRLF for now.

For windows users git can automatically handle LF <-> CRLF conversions.

I strongly suggest windows user who are going to push stuff in to check the git configuration to verify that the core.autocrlf is set to input (to use bare LF:s) or to true (to have CRLF locally).
