quiet flag to hide script name in output

[alxndr]

This adds an optional "quiet" flag to the full script config object, which if set to "true" will hide the script name prefix in the output on stdout and stderr.

[alxndr]

Added this option because without it, the output for a Mocha suite has some, not all, of its newlines prefixed with the script name, thus messing up the nesting nature of the spec reporter. For example, see "[test]" in this screenshot:

Relevant parts of package.json:

"scripts": {
  "test": "npm run test:js",
  "test:js": "babel-node node_modules/.bin/isparta cover _mocha -- --ui exports --recursive --formatter spec test/**",
  "watch": "npm-watch",
},
"watch": {
  "test": "{lib,test}/**/*.js"
},

TBH I'd like to fix the bug as well, but I don't see any harm in having this option as well. Thanks for the PR!

@alxndr any reason this isn't a boolean?

[alxndr]

Whoops, nope!

I'd guess the bug has something to do with stream buffering...
