for agenda, motions, assignments, users and mediafiles apps. Users app: - Show permissions in group form (Fixed #1500) - Added experimental csv import for users. Agenda: - new agenda sort view. - Added experimental angular-xeditable for item-list view. General: - Added core.tag templates. - Added mediafiles templates. - Remove old template and js files. Remove old views. - Skip old tests. Added external angular modules: - angular-loading-bar (Fixed #1448) - ui-tree (for sorting agenda tree) - ng-fab-forms (for better form validation) - ui-bootstrap (for modal window, dropdown, popover) - ngBootbox (for confirm delete dialogs in agenda and users app)
