Eddie Lebow ab0e76dbd5 Use rubocop's JSON output format (resolves #339) (#738)
* Use rubocop's JSON output format (resolves #339)

Rubocop's emacs formatter seems to have changed format in some
not-so-ancient version. The JSON formatter should provide a more stable
interface than parsing lines with a regex.

The JSON formatter was introduced in mid-2013, so it should be safe to
assume available in any reasonably-modern environment. The oldest
currently-supported version of ruby (according to ruby-lang.org) was
not supported by rubocop until 2014.

* Rubocop: Use global function for GetType

* Rubocop: Use scope prefix in GetType

* Rubocop: Update command_callback test

* Rubocop: add end_col to Handle
