Disable curses interface by default about pegaswitch

[SomeoneWeird]

At least 2 of those issues are because of WSL, which the readme says 'works fine without curses' - I'd be cool disabling it by default when we detect windows or WSL

Curses also prevents cut and paste for me in Tilix on Linux, which I find really annoying.

The interface also breaks on macOS Sierra (didn't test High Sierra because that OS is still so buggy) if running node >= 8

I wrote the interface when I was still running Sierra (and upgraded to High Sierra when it came out) and it's been fine for me. Can you explain how it's broken for you?

Running node 8.10.0 or node 9.8.0 (installed via homebrew respectively using brew install node@8 and brew upgrade node from my old 6.2.0 version), I ran sudo node start.js (explicitly using either node 8 or node 9) and what happens is the curses UI comes up with the REPL and Debug panes, but nothing else other than that. Both panes are blank. Exactly the same problem as described in #89.
