LibGUI: Some more convenience functions for constructing widgets

Browse source 
This patch adds two new API's:

- WidgetType& GUI::Window::set_main_widget<WidgetType>();

  This creates a new main widget for a window, assigns it, and returns
  it to you as a WidgetType&.

- LayoutType& GUI::Widget::set_layout<LayoutType>();

  Same basic idea, creates a new layout, assigns it, and returns it to
  you as a LayoutType&.
