Multiple non-MDI assumptions were made, setting CWD and assuming it didn't change. Fix required to pass more context to nodes (functions). It's not totally clean, but it's a start. Fixes bugs: opening multiple files simultaneously only loaded the first file, refreshing an scad file referencing an external file failed if another scad file was opened in the meantime.
