On Windows, default terminal for [Atom's Platformio-Ide-Terminal](https://github.com/platformio/platformio-atom-ide-terminal) is Powershell (at least, that is what I get without any configuration). 

I would prefer a terminal using unix-type commands. I already have MINGW and CYGWIN installed.

How can I avoid opening a Powershell and opening another terminal type instead?
