Fully convert coffeelint example repo to JavaScript

[alangpierce]

This a tracking task for getting coffeelint completely working as a decaffeinate example.

Repo: https://github.com/decaffeinate-examples/coffeelint

All files convert to JS successfully, but there are test failures. The main remaining issue is #801, but it looks like there are some remaining failures after that that need to be investigated.

Another issue that should be fixed before closing this is that there is at least one literate coffeescript file: https://github.com/decaffeinate-examples/coffeelint/blob/decaffeinate/test/test_literate.litcoffee . So probably decaffeinate should be able to convert literate coffeescript before calling this repo done.

The tests all started passing recently, but they broke again today due to a regression with the eslint 3.16.0 release. I tracked the bug down and filed it as eslint/eslint#8116

Tests are all working decaffeinate now supports literate coffeescript, and I also set things up so the Cakefile is converted to JS, so this can be closed.
