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.
E.g. cmake pops up a wizard then, the running of cmake can fail though.
Now you don't end i[ with a empty project then. The error reporting in
that case is not yet optimal.
