Emanuel Schuetze 8d638a908d Added new angularjs templates
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)
