Migrate GuiComponent from having separate handler objects for each facet of its functionality (component.clipping.clipToBounds = false) to having open methods delegated to the appropriate handler (class GuiComponent: IComponentClipping by ComponentClippingHandler(this), IComponentData by ComponentDataHandler(this), ...)

Initially the functionality should remain untouched, with the only change being the careful renaming of fields and methods.
