Fix HTML5 and Angualar.js page

Minor fixes and enhancements in angular.js and html pages from customised version of [login to view URL] 1. Page contains 2 sections. 1 available items to assign and the assigned items. What I would like is to have the items in the available assigned to be greyed out if its already assigned. 2. The alignment of the dropcopy aren't correct and should be no blank spaces between the dropzones. 3. When I fetch data it can take a few seconds I would like some sort of UI feedback to the user during this time. For example a whirly circle or hourglass. 4. Optionally If simple I would like to add another item to type to the model.
