Removed highchart library as it violates the licence policy of Highcharts to bundle it unless an OEM licence is purchased.
Removed Jquery UI and the datepicker. 99% of users will put their own datepicker in and this keeps the app javascript agnostic. Ideally, we should remove Jquery.
Moved inline CSS from range_widget.html and added to report.html.
Chnaged {{ STATIC_URL }} usage to usethe staticfiles app. This helps with future Django version compatibility and also makes it way easier to add your static files to a CDN.
