* Setting the default  `script.escapeConsoleOutput` value in the same place as https://github.com/rgbkrk/atom-script/pull/225 (`Script` top level)
* Revert to the original conditional as proposed by @morinmorin (this converts ANSI codes to HTML regardless of the `script.escapeConsoleOutput` option.
