Use regular Result name instead of __Result__

it's annoying + unnecessary

Are you able to return a rust Result<T, E> from a command? I would like to use ? operator in commands, but thus far have had to create a custom CommandResult<T, E> which means no ? operator.

you should be able to? in 2.0 it's how we support typesafe error handling
