Wizards: Redo sub project handlingHEADmaster

If the user tries to add a sub project the decision for the
parent project must happen directly on the intro page
to avoid asking for build system or kit information later on.
Any of these information are provided by the parent project
and can therefore be skipped in case of having a sub project.
So, move this decision to the first page and on the last page
only let the user decide to which sub node of the chosen
project the new project will be added to.
The old approach set the IsSubproject marker quite too late
to handle this appropriate, so explicitly set this already
on the first page.
For now there should be only qmake based projects which are
capable of adding sub projects at all, but this patch should
be a generalized preparation for having similar functionality
in other build systems.
