Windows support

These are a few changes to better support Windows.  We may want to add a warning to the documentation that we don't really want to support Windows, but are just including it as is.
Not sure if this is clear to everyone, but the main reason prompting this change was that the forward slashes in this command are not recognized correctly on Windows. Since npm always adds ./node_modules/bin to the PATH, removing the relative path components was one way to avoid having slashes at all. This is according to @manthey yesterday.
