• added multi user support (The user defined in appsettings.jaon automatically becomes the first admin user of the application. This user can then create additional users in the frontend and, if necessary, assign them admin rights or assign the corresponding mail accounts that the respective user is allowed to view. When users log in, they only see the accounts they are authorised to access.)
• user credentials are now saved in the database
• added option to exclude imap folders from sync for each mail account in the edit page
