Raw object inspector improvements

[alexander-yakushev]

1. When inspecting objects that don't have special render handling, separate static and non-static fields. Also, sort fields by name. Looks like this:
   

2. Walk the class hierarchy to display not only immediate object's fields, but also fields inherited from superclasses.

Looks pretty cool! Seems there's some small issue with the formatting, the code itself looks good to me.

Also - don't forget to update the changelog.

It looks like cljfmt doesn't understand proper letfn indentation.

[alexander-yakushev]

Should I rewrite it using regular let or are you willing to spend potentially A LOT of time to investigate? :)

[bbatsov]

Probably you can try teaching cljfmt here https://github.com/clojure-emacs/orchard/blob/master/project.clj#L58, but I'd be fine with using a regular let.

[alexander-yakushev]

Turned out much easier than I thought.

Thanks, Bozhidar!

I've also pushed a new snapshot of cider-nrepl.
