Add validation before creating aliases: * Prevent creating aliases outside webroot (public/ dir) * Skip empty "" alias * Skip "/" → "/index.html", which gets overwritten anyway * Refuse to create Windows-invalid filenames on Windows; warn on other platforms * In case of invalid aliases, after skipping them, return `err = nil` to prevent the error passing up all the way to `hugolib.Render()` and causing Hugo to abort. * Update alias tests. Fixes #701: Add support for alias with whitespace Fixes gohugoio#1418: Add validation for alias
