Cleanup display of multiple warnings in T3 (Big font) view: In a very early version a list of possible warnings was shown and the active once highlithed in red. Because of the rising number of warnings and the big visualization of the first warning (double size) a erronous mixed warning list was displayed. This has now been cleaned up. The main warning is still be displayed in double size but the following warnings are shown on the right side in normal fornt size.
