Added Node support.

* Added component.json to add dependency on express server and less compiler
* updated README.md to reflect the same.
* Now one can use `node server.js` to quickly host the package.
Added LESS support for spinner and Menu item.

Also added few additional items in misc.less for form field styling with transition etc.
