QDialog - Change exec() and open() to virtual functions

QDialog is meant for inheritance (it contains other virtual
functions) ...

The main reason for this is that we inside the dialog
could have a (datadepened) precondition that should
prevent the dialog from being shown at all - instead we
might just want to show a messagebox.

That is not easy solvable in Qt right now. It is possible
to reimplement setVisible - but calling reject from
setVisible does not work. There seems only to be clumsy
solutions to that problem - unless these functions are
made virtual

Beside it also creates a nice symmetry to done.
