Project Render - improve exclude only logic

Rather than use a glob like `**/*` (which will expand to include files in hidden directories or which might otherwise be excluded by engines), or a path like `.` which isn’t a glob and thus doesn’t expand, use the `addDir` function to build the render include list (and then use the excludes to filter this complete list). The `addDir` function will add all the files in the directory, excluding hidden files and engine ignore files, thus doing what we need.
