Create more app templates instead of the simplest "helloworld"

From the very beginning till now, I have not seen much updates on the the Qt Quick template app generation. Qt Quick needs to manually key in the text. If we provide more templates (list, grid, pathview, multiple pages) for developers to easily create a bare-bone framework, that will help to produce a lot of good apps. Meanwhile, the templates may further produce good quality of apps. When a template is selected, it is good to show the pictures during the wizard. As such, the developers may know what the template looks like. Please further refer to Carbide.C++ or Visual Studio 2010 express IDEs for further understanding how the process is done.
