Subject: [PATCH 1/2] Use `console.log` instead of `console.debug`

In the browser, `console.debug` does not output anything by default. From MDN (https://developer.mozilla.org/en-US/docs/Web/API/Console):

"Starting with Chromium 58 this method only appears in Chromium browser consoles when level "Verbose" is selected."

Subject: [PATCH 2/2] Add flag to force Node colors

So that process that runs in Electron renderer process can log to
the terminal if it runs in a headless mode, but to the browser console
if it runs with the browser window.

Use case: run browser tests in electron-mocha renderer with or without
browser window.
