[RAPPS] Remove .net 4 again. We have a rule regarding entries in RAPPS. Stuff that works can be added, thats why I ask for pics proving that. I fully confirm a working setup, but thats it. I have no clue how these pics running paint.net were made, but let me add this one: ONLY pics made of vanilla TRUNK as proof please. I will be readded as soon as it really works in TRUNK.
