Missing exit option in the API documentation, and the NodeJS API

[regaldisclaimer]

I commented here initially, but this seems to be an issue to be addressed, not just my inability to locate information.

The new --exit option in v4 is not incuded in the API documentation, and also seems to be missing from the JS runner.

Is this an intentional omission, or should it be added in?

hey @regaldisclaimer, is this issue meant for this repo? I sometimes mix up chai and mocha myself :)

@austince ah, yes. you're right. I was browsing both repos, and must have clicked on the wrong tab. Sorry about that!
