Initial feedback on building egeria-ui about egeria-ui

[sarbull]

Merging #8 will adds the following:

• makes the package independent of operating system, any script command will work only after runing npm install because of adding missing packages under devDependencies(this is explained here [0]) in package.json.
• npm run build (now with prod build, minify for html, css and js)
• npm run lint
• npm test (only chrome is being checked)
• npm start (default start on 8081 using polymer serve command)
• npm run start:dev (uses the polymer serve command with some arguments and proxies everything that's under /api to the mock, if it's not under /api it won't work and you need to use the npm run serve command, due to polymer cli contraints)
