Replace CRLF line breaks in wave_browser which offend some versions of git

It appears that this one file has different line breaks. My local version of git does not seem to mind but the version on our cluster freaks out about it and reapplies these changes any time you try to stash them.

I understand that this can be deactivated in my gitconfig but since it's apparently the only file in this repo with the issue, you might want to change it, for consistency's sake.
