Fix an issue whereby the installer installed cheatsheets into the wrong directory on Windows. This occurred because previously `path.Join` was used where `path/filepath.Join` should have been used. This matters, because the former always uses `/` as the path separator, whereas the latter will use `/` or `\` as is appropriate for the runtime environment. This should resolve bullet point 4 in #665.
