Nocolor

Fix #358

Log part has to be fixed so it won't work on it.
Monit has a weird behavior due to [charm](https://www.npmjs.org/package/charm) [multimeter](https://www.npmjs.org/package/multimeter) dependency (https://github.com/substack/node-charm/blob/master/lib/encode.js). Still maintained?
List ([cli-table](https://www.npmjs.org/package/cli-table)) has a [colors](https://www.npmjs.org/package/colors) dependency that can not be overriden and colors doesn't support `--no-color` (https://github.com/LearnBoost/cli-table/issues/39). 

We could fork all these and try homemade fixes but it'd be a real pain.
