Pressing middle mouse now shows a radial menu HUD element that allows selecting active controlled element. At the moment there only is "Creative Building" but in the future you may be able to select weapons and such. Currently not networked. - Add IntegratedServer to ClientScene - Prevent _Draw from being called by making Player invisible on server - Use _UnhandledInput in CreativeBuilding - Add Cursor.ScreenPosition propertymain
