LibGUI+LibCore: Move GML property system from LibCore to LibGUI
Since Core::Object properties are really only used by GML now that the Inspector is long gone, there's no need for these to pollute Core::Object. This patch adds a new GUI::Object class to hold properties, and makes it the new base class of GUI::Window, GUI::Widget and GUI::Layout. The "instantiate an object by name" mechanism that GML uses is also hoisted into GUI::Object as well.
