Fix reverting a vote without reload

Browse source 
Before it would not work to vote up and immediately vote down again
without reloading the page inbetween. Also added some TODO for cleanin
up the JavaScript into a more reusable widget.
Refactored the code a little to use a constructor for CodeNY and moving
towards a widget architecture.
