Seebi ebde32aa5b Add raw attributes (#26)
* 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
