1. fixed default dialog style to make them non resizeable again

2. fixed wxFrame::IsShown() which always returned TRUE before
3. wxWizard now calls TransferDataFromWindow() before calling
   wxWizardPage::GetNext() fixing an obvious bug
4. half-fixed fatal bug in wxDialog::ShowModal() which would crash if the
   top level app window was deleted while the modal dialog was shown
