Maintenance, dependencies, and improvements

## Maintenance
* Renamed deprecated `component.json` for an updated `bower.json`
* Tested with latest jQuery, removed version blocker
* Some documentation improvements
* Removed trailing spaces

## Improvements
* Fake user doesn’t rely on [web service](http://www.roughdraftjs.com/api/) anymore, but through `localUserThesaurus`
* Added `localUsers` in  `roughdraft.thesaurus.json` for `localUserThesaurus`
* Refactored test/ examples, removed checked-in jQuery requirement, called more recent jQuery from CDN

## TODO
* Create tag to upstream ndreckshage to `0.1.5`  as `bower.json` is declaring it
* Minify `jquery.roughdraft.js` into `jquery.roughdraft.min.js`

## Soon

Next objective: Propose default configuration that doesn’t require ANY HTTP calls for images, users, text.

Also:
* Build process, linting
* Implement automatic image generation, based on [this small SVG image generator utility](http://schepers.cc/svg/svg-datauri-img), thanks @shepazu (!).
