New Features:
* Adjustments have been made to the login screen:
- You can now login using a QR code. The QR codes are available on the respective website in the group manager (for group masters).
- The app now remembers the website with the last successful login and selects it as the new default when adding a new account

Bugfixes.
* Fixed a bug where images could not be removed during storyboard creation.
