Drag and drop feature still doesn't work correctly. It's possible to drag and drop one activity, but if you try to drag and drop a second activity the app crashes.
The problem is, that for the second activity the 'dragstart' event is not fired. The root of the problem is the last line in the dayController.js for the 'drop' element. The model gets updated and then the dayViews are recreated and the function doesn't seem to exit correctly...
