Proposed interface changes

Fixes most of [#42](https://github.com/privly/privly-chrome/issues/42)
* Removes radios that confused user by auto saving with a drop-down and made 'save' compulsory
* Replaced text area with multiple input text elements with option to add more elements dynamically
* Made changes in the js file to accomodate new UX
* Made minor additions in css for new elements
* Removed clutter text and retained only that text which matters and for a good UX
* Layout change not majorly made. After seeing the code, it fees the power of bootstrap has not been used properly.
