Fixes #59

Thanks Eddie for the patch!

I also made a few changes:
- using common Piwik function Piwik::sendHttpRequest to fecth remote data
- added error use cases (empty data back, feed is not authorized)
- cleaned up CSS
- when the feed name is updated, the widget will automatically reload (added helper functions in dashboard JS object to reload a widget)
