Issue #26 & #28 & #31

This fixes issues running the demo, but also aligns more closely with cicero-ui and other AP lerna-based repositories:

• Switches the demo from react-scripts to webpack
• Changes the lerna build to use hoisting
• Aligns dependencies across all packages (as much as possible)
• Upgrades to react version 16.11 and other dependencies for consistency with cicero-ui
• Adds other dependencies found in cicero-ui notably for styling
• Fixes to tests, adjusts configuration for testing linting and license check
• Enable CI with Travis
• Automatic deployment of npm packages through Travis

So much better, thanks @jeromesimeon!

A few little questions:

1. I notice that you rightly removed most of the compiled code from the dist folders, is there a reason for retaining files in packages/concerto-ui-react/dist/?
2. Has Travis been set up to match the key that's included here now?

No reason, I just missed it! Removed now.

It has... we'll know if I got it right as soon as we publish a new release.
