fix for real player status being sent on client-side.
add car.html which can communicate with Pandora's Box. Note that this is a modified WD_Standard.js file, sending AJAX requests to the WD web server, because we are not hosting car.html on Widget Designers built-in web server. It is probably a GOOD idea to actually run these client-only files on the WD web server, because for now we are running into CORS problems etc (and plus, we have to run a 2nd server to run the client files (although I saw somewhere that Sinatra can be run within an EventMachine server, so we could use that for both serving static files and the WebSocket server)).
update .gitignore to ignore bower_components
add README.md with instructions. Game correctly allowing a maximum of 2 people to join the game.
