Colorful error messages

[baransu]

Currently while stumbling upon error, messages are single color.

While building using bs-platform from CLI error messages are nicely colored.

I was trying to find where the problem is but I don't know which part of the stack is causing it (reason-scripts, bs-loader, react-dev-utils/WebpackDevServerUtils or maybe webpack).
I would really like to work on PR bringing colors to error messages 🙂

Hey @baransu! Thanks for opening this issue 😄

This would need to be done in the bs-loader repo. Right now bs-loader pretty much does "exec('bsb -make-world')". We would need the NodeJS "exec" call to capture the colored output from bsb and then return it to Webpack.

It's awesome that you'd like to make a PR to fix this! I recommend checking out the bs-loader source code, and the documentation for NodeJS's child_process library
