Rework the project settings.
This has still a few missing things, but this enough to start getting some feedback. Missing are non qt projects, a solution for the runconfiguration, a missing black line between the treeview on top and the project settings at the bottom. Some flickering with removing/adding widgets to the QScrollArea and not showing the expanded widget if the Details button is right at the bottom.
