* QtProjectWizzard handles window managment logic of project setup
* QtProjectWizzardWindow is used in every step and displays QtProjectWizzardContent
* QtProjectWizzardContent is the base class for all differnt content types
* Removed Singleton from ProjectSettings
* ProjectSettings are created by wizzard and QtProjectWizzardContent can access and load
* added project type selection at start of wizzard
* added summary at end of wizzard
* show global search paths in setup and summary
* fixed layout problems after font switch
* fixed scrolling and resizing of QtDirectoryListBox
* separated QtLocationPicker to own class
