Project Wizards: Introduce notion of project directory, polish.

- Introduce project directory and "use" flag to file manager, use that
  in new item dialog
- Add configuration under Project settings, rename it to "General"
- Make wizards create project names as "untitled1.."
- Remove modules page from Qt application wizards (parametrizable)
- Give Utils::ProjectIntroPage a "Set as default location" toggle.
- Introduce wizard dialog base classes for handling that.
- Introduce notion of "last visited directory to file manager" for
  open and non-project wizards, route open through file manager.
- Clean out QmlAppWizard
