Add docs to completion

Resolves #513

Well, that was simple enough. Not sure what I referred to in #513 (comment). Is it possible that Racer started also including docs in the completion data in the meantime?

Thanks!

Yeah that's what I assume, lsp supports markdown docs now too so everything lined up nicely :).

Just curious, when this build will be available on a nightly Rust version? Today's nightly still contains

rls-preview 0.128.0-nightly (7d0bc55 2018-06-07).

@pravic the commit in the nightly releases is the latest submodule commit reference to this project over in rust-lang/rust. It was last updated about a week ago by rust-lang/rust#51407.

@nrc will usually raise prs to update it fairly frequently, you could even raise one yourself. Another option for the impatient is to simply checkout rls and build it for yourself. Your client should have a decent way to allow this. I do this myself currently because I like clippy.

Thanks for the advice. I'll try to build it locally. Lack of documentation in popups (among others) is really frustrating.

Works excellently. Thanks again!
