We split off the evaluation engine part of nu-cli into its own crate. This helps improve build times for nu-cli by 17% in my tests. It also helps us see a bit better what's the core engine portion vs the part specific to the interactive CLI piece.
There's more than can be done here, but I think it's a good start in the right direction.

Also moved some code to documentation.rs to avoid making help.rs massive
* Delete summaries.md

Which will be used like
'help generate_docs | save "something"'
The resulting yaml can be passed to a script for generating HTML/MD files in the website
