Suggestion:

• [x] Allow users to define a template for the white area in the main screen with a placeholder for the login form.
• [x] When the place holder is missing a warning is logged and the template is ignored
• [x] Provide a nice looking default template for test systems based on the above mockup. Suggestion: Add default login buttons on the left side of the login form
• [x] Move HZI, Symeda and GIZ logos to the source code (instead of default template)
• [x] Add missing default users to startup backend logic
• [x] Remove "Login as default user" button
• [x] Small text changes
• [x] Replace hard-coded text in the sidebar with I18n strings
