Fix: tons of fixes and improvements.

After fixing my development environment, I went on to fix some issues with
the code.

RSS Entry body is now unique and the model validates uniqueness of body,
uri and original uri.

Refactored get_url_without_params() with a simpler and leaner implementation.

Wrapped the feedjira parsing in a begin/rescue to catch faulty feeds.

Implemented very basic templating to improve presentation.
