Change line endings

This file caused huge mess. It comes from Windows and has those
crazy CRLF line endings. Somehow it jumped to my repository and
prevented all other work before it was saved with proper line
endings. Absolutely useless fix. This seems to have cropped
somehow from R-Forge...
more crap due to mysterious CRLF ending up in files...
Merge branch 'master' of github.com:vegandevs/vegan
remove the remaining CRLF from files.
Merge pull request #58 from gavinsimpson/fix-more-crlf

remove the remaining CRLF from files.
