Added Chart template

Hi,
I have added html, css and js files to load charts.
You can run python manage.py runserver and goto 127.0.0.1:8000/templates/chart to see the template in action.
Note the data is static, and is where you should come in and load it using queries made to the server.(Have a look at occupancey/webApp/static/webApp/js/my.js, find out where data is and that is where django templating construct should be used)
For the above I have made changes to Urlconfs of our app. Also I have replaced the now deprecated way to define urls with the new ones. My django version is 1.6. Let me know yours too.

To be done: Add a a central graph in the "middle-column", for better clarity of data.
