Open recent IFC project #3657

Example - https://imgur.com/a/EDfBTJS

Paths to the opened IFC projects are now stored and then you can open them from File -> Open Recent IFC Project menu. It's done in very similar way to how Blender does it, list of files is stored in `Blender\4.1\config\recent-ifc-projects.txt`.
