Separate console output and test results

[Nithanaroy]

./node_modules/mocha-phantomjs/bin/mocha-phantomjs -p /Applications/phantomjs-2.1.1-macosx/bin/phantomjs ./test/index.test.html --ignore-resource-errors prints to stdout - console.logs, console.warns, console.errors and test results intermingled. Would be really nice if we can separate everything into groups or turn off console output completely.
