Remove CRs from text files and add newlines at end of files (fixes #8)

The CRs were probably added when edited from a Windows editor or an incorrectly configured *nix or OSX editor

See http://stackoverflow.com/questions/729692/why-should-files-end-with-a-newline for rationale on newlines. (git complains if no newlines are found, too: "No newline at end of file")
