Now supports both CoffeeScript and javascript

I updated the generator to support a language option, 'language = coffeescript or javascript
I also changed application.html.erb to generate the ng-app argument so that it derives from the Rails app name, e.g., Rails app 'Sue' has an angularjs client called 'SueClient'.

I am thinking about extending the generator in index.html to include all attribute columns, excluding id, and the datetime attributes.  

I welcome feedback.
