Exposed the reading modes for extensions through Minz (#7668)

* + Exposed the reading modes for extensions through Minz. Now extensions can add a custom view mode. Graceful fallback to normal view in case the extension was disabled without resetting the view_mode through the uninstall method. In that case the user will be informed via Minz_Request::setBadNotification that the view has been reset to normal.
+ Added translation strings for de, en and en-us for the notification

* + Added missing, generated translations

* Simplify indexAction, performance

* Minor settings htmlspecialchars

* i18n: fr

* Minor wording

* Doc

* Fix i18n
