* Add raw attributes This makes it possible to call clap functions that don't take strings, but any arbitrary value. Even functions that take more than one argument can be called. All attributes that are called `attribute_name_raw` are augmented to `attribute_name(value)` without quoting `value`. * Add tests for raw attributes and fix spelling
