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`.

I think something like .expect("bad parameter to {}: the parameter must be valid rust code", key_with_raw) will help debugging

Thanks for the review, I added some tests and fixed the rest. |

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_raware augmented toattribute_name(value)without quotingvalue.This fixes #4.
For enums, I changed
AppSettings::SubcommandRequiredtoAppSettings::SubcommandRequiredElseHelpif that's ok?I find it much more useful if an application lists the help instead of telling me to get the help manually.
