No color coding in terminal

Problem

When I run elm-brunch, I get monochromatic errors:

That would be a great feature, don't hold back if you want to submit a PR for this.

I think this is caused by elm-make failing to detect a TTY (a "proper" terminal) [1] because it is executed by brunch. The canonical solution seems to implement a command-line flag in elm-make [2].

@niklas That's incredibly helpful. Thanks. I'll file an issue with elm-make and possibly work on it if I can find time.
