Finally, a way to actually add an IFC element directly

Previously, the way to add an IFC element would be to 1) create a blender element then assign or 2) activate bim tool, launch type manager, click create type, fill out field, or 3) using various menus for parametric stuff like stairs. This is now the new proposed way to do things and everything will consolidate to here - and it allows you to directly create non-mesh geometry immediately too!
