Dev dependencies

[booleangate]

Just did the following to remove dev dependencies from the production dependencies.

npm un --save chai chai-as-promised eslint mocha mocha-better-spec-reporter
npm i --save-dev chai chai-as-promised eslint mocha mocha-better-spec-reporter

Tested with

rm -rf node_modules
npm install --production
npm start
