Created dummy GuiOverlayElement interface for ComposedElement to determine which Elements to draw last

Added methods to retrieve position and size from a GuiElement
Added draw() method with option to override hovered boolean to GuiElement interface and implemented it. This is required for GuiAdvancedButtons which would be tinted blue (as if hovered) even though an overlying GuiElement (e.g. GuiDropdown) was hovered
